I recommend propane, propane, propane. I have converted my 74 F-250 4x4 with a 351w (the engine was a project in itself) Also i converted a 77 Crysler New Porker with a 440cu, and i am currently converting an 84 ranger 4x4 with a 2.3 turbo to solve preignition. later this year i am to do my fathers 67 Merc F-250 with a 390. Propane is more commonly found than natural gas (at least where i am) It is only 10% less powerfull than gas, compared to natural gas at 25%. the 10% can be made up for by bringing up your compression to 10 to 11.5 to 1. Because propane is about 105 octane. Also you never have to worry about bad gas, cold starting, the carb freezing in the winter, if you offroad the propane mixer (carb) doesnt mind the abuse. I can go on for ever....... I love the stuff. Jeffrey Osier-Mixon wrote: > > I have a '68 F100 longbed with a '70 390.

Anyway thanks for provin my point Tony :) I say: YES!!! I know what you are talking about. Wide wheels on a 4x4 are one thing but the "hot wheels" look so popular with kids these days makes me want to puke! The only good thing about the look is that these idiots won't have a driveable car for very long. And if they do force any distance out of their tourtured cars then maybe we can thin out the gene pool a little. STUPIDEST thing I ever saw was a T(riceburner)a 4-runner that had 13 inch wheels, extralow profile tires that were extra wide AND the truck had a LIFT KIT!

You asked for it. My opinion is to use an inductive pickup, powered timing light with a xeon strobe tube to set the timing to spec. Paint the mark on the harmonic balancer and the pin or degree marker with white or silver paint. Testor's model paint works great for this. IMHO any other method is strictly guess work and is only good to get you by if you are stranded or desperate. Tune up steps: 1. replace any parts that don't function 2. Clean and gap or replace spark plugs (do the whole set) 3. replace points and condensor if so equipped 4. replace rotor and distributor cap 5. replace spark plug wires if needed (again, do the whole set) 6. replace air cleaner 7. Set dwell angle with a dwell meter 8. Set timing with a timing light 9. adjust carb using a tachometer 10. set curb idle using a tachometer 11.

It was the negative battery cable after all... Well I know I said I already checked it thouroughly and cleaned the connections at the engine and at the battery. Note that I also have a #10 gauge backup ground cable to the frame. However the main cable is one of those that you cut you own length and then bolt the connector to the cable with a clamp. Well I noticed it was corroded under the clamp and under the sheathing. I cut about an inch off and stripped it and reconnected it. VROOMM! It fires up real strong even before I can get the key turned all the way! I had also tightened down the carb, but I think it was the battery cable. For the record, before it was fixed, it usually turned over basically normally but only for 4 or 5 cranks. after each retry to start it would crank fewer and slower until a click. The only other thing I havent already mentioned was the fact that the problem showed up suddenly. within 3 days it went from no problem to never starting when hot. Also, in addition to what I percieved as MILD green corrosion in the wires mesh in the battery cable showed signs of spark burns and were somewhat brittle. I figure that moisture or shorting at the connection caused sparks, ruining the connection and causing my hot starting problems. in addtion to that there was rust on the underside of the clamp ( cable itself is prbably only three years old.) See my previous posts for further symptoms. The question remains... Would it not start when hot basically because of the starter being hot? Thanks All! Date: Sat, 05 Jun 1999 09:06:18 -0700 From: "O'Connor" Subject: FTE 61-79 - Hot Starting John, Saw your response and I've added the warped flywheel to the chart. Don't know if it was related to slow turn over or not. Would appreaciate if someone would report in and let us know if this was a real fix or just a hunch and if it turned slow. John, also you reported that your truck turns over slowly when how. I think that is the key to the problem. I had a 56 Chubby that turned over slow when I shut it down and would't start intill it cooled. I did discovered that if I parked it on a hill I could pop the clutch it would fire off. That real embarrassing on a date! Hot starting- slow turn over Hot starting- normal turn over antifreeze buildup Vaporizing fuel Bad ground at starter??? Bad ground at starter??? Warped Flywheel??? Warped Flywheel??? If the guy that experienced the ground problem would report in and let me know if it turned over slow or normal, I can put it in the proper column. == FTE: Uns*bscribe and posting info http://www.ford-trucks.com/faq.html ------------------------------ Date: Mon, 07 Jun 1999 08:35:40 -0500 From: William S Hart Subject: Re: FTE 61-79 - building a 390 GT out of a 360 >Hi I have a 1971 360 and I want to make a good 390 out of it.

I would double check the timing, set the balancer at TDC and then set the distributor at the #1, mine was doing the same thing when I went for my 390, I recognized it instantly as an advance problem (you just know after it happens a couple times), retarded the thing back to near 0 and it fired right up. Didn't set the timing til after cam break in and everything, just as long as it runs okay you should be fine.

The different cam will want a different timing setting than spec'ed by the factory. One way to set the timing is use a vacuum gauge (or tach) and set it with as much vacuum (or revs) as you can get, then see how much pinging you have, back it off a couple degrees at a time until you don't have any ... then maybe add one and see if it pings or not ... this may take a while, but once you get it, WRITE IT DOWN! That way you can get that timing set again more quickly and use the timing lite to set it.

The pushrods have to match the rockers, so for example if you have 69 heads, then you have to use the early 302 style pushrods. The 302's also use a smaller head bolt, I believe a 7/16, while the 351 heads are drilled for 1/2 bolts, so you'll have to use a hardened washer to take up the space. Torque to 302 specs.

The solenoid is on the passenger side fender well, correct? Kind of next to the battery. Perhaps your problem is a bad ground at the fender. This has caused me a lot of problems. Not with starting but with my voltage regulator, which is also grounded on the fender. It would blow up at long trips, say 300+ miles a day, and just boom the voltage to 20 volts or something. The battery started boiling and sprinkled the whole engine compartment with acid, no fun. Four regulators later I added a ground wire from my regulator directly to my alternator. For the last 5000 miles or so it's been keeping up great, including 1000 miles driven in 2 days. Since I never had problems when driving around town, I thought maybe you have a similar problem.

Can you tell whether the click is just in your dash or also under the hood? With my '78 bronco it seems that there are two relays.

When I disconnect the battery I don't hear the click. If you can determine whether or not the relay on the fender works in case 3 you are closer to the solution. >One guy told me to check at night for any sparks around the motor especially >the distributor but there were no sparks.

Either I'm the worst wheel bearing grease packer in the Ahh, one of them went on my '78 bronco too. I bought the vehicle last summer and the front end had been working quite peacefully. Then I had some dirt in my bead because of 4wd activities so I took it to a gas station to have it fixed. The monkey who did it jammed the wheel on there without too much care and pushed one of the studs inside! And that on a thursday night. He said the mechanic could fix it the next morning so I took a taxi home. When I came back the next morning the mechanic said he could fix it - for $70!! No freaking way are they going to make money on me like that. I had it towed to another shop and had THEM fix it, and repack the bearing at the same time. It turned out that my hub was indeed worn out, which is why the stud could be pushed inside. Funny though this never happened to me... Then next weekend I repacked the other side myself. A month later the truck started vibrating worse and worse, and whenever I put it in 4wd the left front started squealing and grinding, probably the u-joints. Also I had brake problems. Vibrations are hard to diagnose, and the same goes for the brake system, so I took it to a 4wd shop friends of mine had good experiences with. He (Chuck) found out my rotors were warped (still not sure how that happened), and the bearings that the shop did earlier were just about to break down on me. My side was fine. Further investigation learned that they had grease in them and were not over-torqued, but water had come into the bearings, so whether or not the guy at the shop was at fault, I don't know. He may have used cheap grease. I know he did replace the seal. The u-joints in the axle were indeed the source of the squeal, they were ejecting rust and all the bearings were gone!

Amongst the gobbledegook, the state legislature is trying to please a) The Feds b) The people, in the order of whomever is screaming loudest, or withholding the most money. A few years back, the state tried to institute a new smog check program, over the threat of the feds withholding highway funding if we didn't. The feds were whining that is was just too easy for anyone to get around the bi-annual smog checks. There was a $200 limit on the repairs, beyond that a waiver was granted, or, if you knew that right person, you could just buy a smog certificate. The new program was to close down the existing network of inspection stations (generally, service stations and/or repair shops), and replace them with 'Official State Smog Stations'. These stations would do full dyno tests, and COULD NOT do any repairs. Here in Sonoma county, that would mean replacing several hundred smog inspection sites with TWO! Along with this, non-compliant cars would be labled as gross pollutors, and could be seized and crushed. Well, the people were pissed. And, the laws were revised :-). Among the changes were: Existing stations remained open, certificates are now electronically transmitted so that you can't buy one at the flea market. Repair limits were increased to $600-$700, I believe you can only get one waiver (you have two years to fix or get a new car). 1973 and earlier cars are now exempt :-)! You can still have your car labled as a gross polluter, but most shops abort the test before it gets this far, unless you managed to pick a shop having a bad day :-(. The only car crushing that I'm aware of now is being done by large corporations buying pollution credits. The corp will set up a 'buy your clunker' process, were they will buy your licensed gross polluter for $700-$1000. The car is then crushed, and said company gets to expell a few hundred or so more pounds of stuff into the air. These buy backs are usually conducted with a knowledgeble auto enthusiest around to ID possible rare or desired Ford Trucks (FTE content), which are purchased and resold somehow. It looks to me that they are evaluating setting up funding to repair cars rather than toss them, and perhaps adding more control systems to pre-EFI cars? The state realizes they are spending X dollarsto reduce emmisions by Y pounds, can the money be better spent by repairing the 'gross polluters', which typically belong to the people who can least afford to buy a new car, or even repair their existing cars? BTW, starting in 2003, all autos/trucks 30 years and older will be exempt from smog inspections. - -- Pat Brown Back from Cabo San Lucas, were the Tequela reserves are just fine :-) == FTE: Uns*bscribe and posting info http://www.ford-trucks.com/faq.html ------------------------------ Date: Mon, 07 Jun 1999 12:45:44 -0500 From: "Jason & Kathy Kendrick" Subject: Re: FTE 61-79 - Alternative fuels, anyone?

If I hold my finger over it, I only feel a vacuum when I punch the gas. " This is referred to as ported vacuum. It is supposed to provide access to manifold vacuum after the throttle butterflys have been opened to the point that the port is connected to the manifold vacuum. This is to allow the vacuum advance to come into play after the vehicle is in motion and the engine has reached an rpm above idle. When the engine is idling then there is no vacuum advance. As you have probably noticed that when the timing is advanced at idle the motor rpm increases. More about that later. "The line was originally routed through some sort of temperature switch on the "thing" the upper radiator hose connects to. Intake manifold vacuum was routed there as well. Since there was no vacuum whatsoever (cold, warm, any rpm) on the other side of the switch I bypassed it. Does anybody know what this switch is supposed to do? I figured it is something that reduces emissions at a cold start." I assume the "thing" is the thermostat housing. The switch you referr to is indeed a temperature switch. The way it operates is to connect the center port to either the upper or lower port depending on the coolant temperature. The upper port should be connected to the ported vacuum connection on the carberator. The lower port should be connected to manifold vacuum -- probably on a tree at the back of the intake manifold. When the coolant temp is low the vacuum advance is connected to the ported vacuum (upper port) and as stated there will be no advance at idle. If the advance has been set to factory specs then the idle speed will be low. If the coolant temp goes up above the switches limit (engine warm stop and go traffic, air conditioner running etc.) then the vacuum advance is connected to the manifold vacuum. Again if the timing is set to factory this will increase the idle speed and increase the fan speed more air flow across the radiator more coolant flow through the engine this should help cool the motor that is warm and idling. If the motor is at speed then this will have no effect on the overall performance of the motor because off idle the ported vacuum and manifold vacuum should be the same. "I tried using my manifold vacuum but that pulls the ignition to about 30 BTDC right at idle, that can't be right. Unfortunately I do not have the vacuum diagram for this engine. But frankly the vacuum advance does not seem to be doing a whole lot. If I look at my timing while cracking open the gas, it only advances after a second or so. Does anybody know some backyard mechanic type of tests I can do to find out more about this?" What year/engine combination is this? It sounds like the 390 in my 76 and if so the above discussion covers the entire vacuum circuit. It sounds to me that your vacuum advance is working properly. You connect it to manifold and advance goes to 30 (it advances). When connected to the port the behavior sounds correct. Think about what is happening here ( you can verify with a vacuum guage connected to manifold vacuum) At idle the throttle butterflies are closed you have 8 large cylinders sucking against that restriction and you have the highest vacuum reading you will probably get from that engine. When you open the butterflies the restriction in the intake tract is reduced allowing more air flow (this is what you want because you wanted to increase motor speed right?) At the instant the butterflies open the engine speed has not increased so therefore the air flow has not increased. With less restriction the vacuum drops dramatically. As the engine speed increases if the butterflies are held constant the vacuum will rise again as the airflow goes up and the open butterflies (at any position including wot) eventually become a restriction again and vacuum rises. This vacuum drop is immediate at any increase in the opening of the throttle butterflies. To test the switch try blowing through the center port (engine off) and see which port the air comes out of. To verify operation remove the switch and heat it in a pan of boiling water and see if the switch changes which port is connected to the center port. Sorry for the long post but hope it helps.

I was planning on finding a new bed with less rust spots on the sides but since they arent rusted through i was wondering if that was really necesary. i plan to paint the truck within the next 3 months and cut out the wheel opening and install replacement panels if i keep the bed. My question is this. if i strip the paint and sand the rust spots down, maybe even chemically strip it, will those spots come back to haunt me after ive spent my money getting the truck painted? the door skins are also rusted at the very bottom, should i get new doors or just new door skins? one more question, both axles are 8 lug and i was told that they may be dana 60 axles, anyway to tell for sure? thanks for any help you guys can give, Ian Coil == FTE: Uns*bscribe and posting info http://www.ford-trucks.com/faq.html ------------------------------ Date: Mon, 7 Jun 1999 12:36:36 -0700 From: "Bill Beyer" Subject: Re: FTE 61-79 - 79 rust and axle q's Could be 60's more likely rear 60 and front 44 tho'. Check the #'s on the tags or the casting #'s on the top of the web by the pumpkin to see for sure.
