I like it, but it isn't the best low end cam. It still has plenty of power off idle, but when you hit about 2000 RPM it really pushes my truck hard. What kind of mileage you get with it depends on your intake, carb, and exhaust. I have a stock 4bbl carb with stock intake and exhaust and I can get 12 or so when I'm not into it.

These were in my truck when I bought it and am wondering what your thoughts are on reliability and accuracy. In particular, the OIL PRESSURE GAGE. This is a direct hook-up to the engine via a small diameter translucent plastic tube. I can see oil droplets in it. Should there be air pockets in it? Does this line need to be bled first to yield a proper reading? If so, how is this done? The temperature gage is connected to the top of the intake manifold via a stiff wire which I am assuming is actually a thermocouple. I am looking for a manifold vacuum gage to go with these two so that I would have three direct readings of engine performance. Also, why all the emphasis on ammeters? Isn't a voltmeter a better indicator of impending charging system doom? Thanks for the read, Jeff (yes, my F100 did originally have air since the heater box in the engine compartment has stubs of "in" and "out" Freon lines sticking out of its inboard side. I have an old York compressor from an AMC and may eventually cobble the system back together with junkyard pieces...that is if I can steal some R-12 from somewhere) ---- 00-04-19 13:17 ---- Sent to --------------------------- -> 61-79-list(a)ford-trucks.com ------------------------------ Date: Wed, 19 Apr 2000 13:15:49 -0500 Subject: Re: direct oil pressure gage From: "John LaGrone" > This is a direct hook-up to the engine via a small diameter > translucent plastic tube.

I swore to never have one like that again. If memory serves me, you don't have to bleed it, but if the plastic is old and split you will lose pressure to the gauge as well as crankcase oil. -- John jlagrone 1979 F150 Custom, Long Wide Bed, Regular Cab, 351M, C6 (Henry) http://www.ford-trucks.com/jlagrone/henry.home.htm Dearborn iron rules!!!! ------------------------------ Date: Wed, 19 Apr 2000 14:23:51 -0400 From: James Oxley Subject: Re: 77 F100 AC vents ???

I replaced the whole unit with one from a '79 Bronco and still no working fuel guage, but what the heck, everything else works like a gem; even the Ammeter!!! Another project for another day :) Fighting fuel gauges on recently purchased vehicles is a favorite past time around here ... I have had to fix the one on the truck about 7 times ... the first 5 were because the truck is wired for 2 tanks but only has one ... and when you plug the spare wire onto the transfer case it grounds the gauge out and reads full all the time ... To check the gauge I'd start by crawling under the truck and finding the sending unit on top of the gas tank ... unplug this and look inside ... there should be a plug or 2 in there. Ground this against a bolt or something on the chassis (be sure its a good ground) ... then go turn the key on and look at the gauge, if it reads full then the gauge itself is okay ... I'd check the terminals then to be sure they had a good connection. If it doesn't move at all, start checking wiring and such to see if there are any bare spots or cuts. If all this looks good, then try replacing the gauge itself (sounds like you've already done that) ... If all the connections are good and clean, then the problem is either the sending unit or the float is on the bottom of the tank... if you hear something rattling around, then its probably a sunk float and you'll need a new one, or to dry the one you've got out and solder it up. The sending unit isn't hard to replace, except for the whole drop the tank step ... then there's a locking ring that you can tap to unscrew (actually just a quarter turn lock maneuver like the gas cap itself) ... then it should all slide out through the hole in the top ... anyway that might be more than you wnated to know... be sure you don't have much gas in the tank when you attempt that, its HEAVY (7lbs/gallon + tank weight adds up fast!)

The >F250 TC adapter is about half the size of the Bronco. I have to assume >the outpout shaft on the F250 trans is also half the length. What was >the reason for this. I would have to guess that they were afraid of drive shaft lengths is why they put the extra extension on there, but I can't really believe that the front drive shaft would be any shorter on a bronco than on an F250 since they're essentially the same from the grille to the back of the front door right? But I wonder if the shorter wheelbase would be more prone to a torque steer of some sort if the drive shafts are vastly different lenghts? Also I'd think you're more likely to lift a bronco than a 250, so the equal length drive shafts (or closer to equal) would make it easier to lift ...

I have had success with running a product from GM called Auto Tune Up/Conditioner in a can. You pour 3/4 of it down the carb with the engine running. Then stall the engine and pour in the remaining 1/4 can. Let it sit for 15 minutes and then start the engine. Lots of smoke will come out your tail pipe. Too much carbon build up in the cylinders increases your compression and then your vehicle will ping on the low octane gas. It then makes it hard to time because you start timing it where it diesels in order to stop the pinging. It has worked for me on a couple of motors. ----- Original Message ----- From: To: <61-79-list Sent: Wednesday, April 19, 2000 1:34 PM Subject: [61-79-list] Dieseling > Matt writes: >>I am having problems with the timing in my truck.

He bought it for 175 bucks last fall, go it running, then parked it out back. I'm considering buying it, but I was just wondering what you guys out there thought. It'll need some rust repair on the cab, and there's no bed, but since I won't have it on the road for awhile, that's no problem, I can always manufacture some flatbed or something.

Can I just purchase factory replacement adjustable type rockers and use them on my non-adjustable type shaft? In one of my catalogs it lists two different part numbers for the shafts, anyone know why? Anyone recommend a source for this, I know crane has a kit to convert the rockers. >>>>>>> What I have are Federal-Mogul 1.76 adjustable stock type rockers. You have to get solid-lifter shafts and ball and cup pushrods. Here are the part numbers: SEA/RS720 Rocker Shaft. Solid-lifter style, 2 required. List $28.78 each. SEA/R821 Rocker Arm. Adjustable 1.76 ratio, 16 required. List $14.32 each. SEA/RP3230R Pushrod. Ball and cup style, 16 required. List $11.94 each. If you are going to rev hard, you may want to consider end supports available from Dove Performance parts , Part Number 82106 $160 kit and Spacers, Part Number 82115 $30 kit to take the place of the springs on your rocker shafts that tend to let your rockers walk around. I don't have the end stands, if I break a shaft I'll get them. Another modification I've made is to put my stock aluminum rocker stands on the bandsaw and cut an open slot in one side to make them clamp the shaft better. Do this at your own risk, though, and be careful to not take any more away than you have to. It kills vibration. I also place a #90 jet out of a Holley under the rocker stands that supply oil to the shafts to restrict the oil. Just press them in and install the shafts. Be careful when you disassemble though to make sure they don't fall somewhere bad when you lift the stand. That's all I have to say about that. ------------------------------ From: "G & J Boling" Subject: Re: 460 Pilot Bearing Date: Wed, 19 Apr 2000 20:48:54 -0400 what i have done a few times on bushings that are ALMOST the right size but too tight to install into the crank is freeze them in DRI ICE WORKED FOR ME GORDON ------------------------------ From: JUMPINFORD Date: Wed, 19 Apr 2000 22:00:31 EDT Subject: Re: 460 Pilot Bearing < WORKED FOR ME GORDON>> Great idea, but what bushing did you start with?

First. Buy Quality Headers! You can easily tell quality, even without actually seeing the headers; though it do help to see em. The Flange(s), the one that is bolted to the head will be 5/16" thick minimum. If it is any thinner pass em up! Look thick gage tubing (14/16Ga.). Second. Most headers are welded to the Flange(s) from the head side creating a kind of "O"ring around the port. This must be FLAT and the same height on every port. If your having problems look at this ring carefully and see if it is low in the area that leaks. If it is you have 3 choices: File it flat if possible, Weld it up and then file it flat, or replace the header! Third. The tubes should be "Brazed" to the flange on the outside with a nice smooth radius. This will increase both the sealing and the life of the header. You can do this yourself, but you must bolt the flange to a head while it is being done. Most machine shops will practically give you an otherwise junk head if you are a customer and tell em what you want it for, some will even take it back when your done! I have found that sand blasting the area helps immensely with the brazing. Make sure that the bolts sit flat after doing this. Fourth. Stainless steel headers will out live mild steel 10 to 1. and cost 10 times more! The flanges on Stainless steel headers if one piece must be mild steel if you want them to seal in the long run. Fifth. As mentioned if you are experiencing sealing problems soak the fiber gaskets in water before installing. If you really cant get them sealed soak two gaskets overnight and stack em, then pull the bolts down snug and fire the engine. Get it warmed up and shut it down. When it is stone cold and not before tighten the bolts back up. Then check the bolts every day for a week. If this don't do it, you need to rework or replace the headers. Sixth. Never over tighten the header bolts! They only need to be tight enough to not back out. If you over tighten the bolts and you have thin header flanges you will bend the flange(s). Once this happens you will not seal em and have to rework or replace em. Don't use never-seize on header bolts. Most never-seize compounds cant take that kind of heat. Use Calcium Carbonate instead. Yep dipping your bolts in antacid is a sure fire way to prevent heartburn later when the bolt is stuck in the head! Seventh. The reason gaskets fail is heat not pressure. If your engine is out of tune it can generate excessive temperatures in the exhaust system. Cast iron manifolds can tolerate this heat slightly better due to their greater mass. But, even Cast iron will warp and crack! If the header is in good shape and your failing gaskets check you timing and mixture settings chances are their off. Eighth. Do not use Lock-Washers on the head flange. They wont work in the long run and will chew up the header. The Lock-Washer is made out of a heat treated steel that it designed to dig in and resist turning by being a spring. If you repeatedly heat and cool a lock washer it relaxes and no longer acts like a spring; the second that the lock washer relaxes the bolt will be loose! The amount of torque required to properly set the lock washer is often higher then the bolts should be tightened to. Safety wire, Stage-8, or just check em once in a while. Ninth. Flange bolts should be Grade 8. Grade 5 will stretch real fast and you will leak. If you remove the flange bolts and they have been in use more then a year, replace em. Tenth. Fix all leaks as fast as you can. A leak will locally heat the flange and can erode it making it difficult to ever get it to reseal. Later.

I'm Marty from South Dakota, I was lurking on the list about 7-8 months ago, but had to stop to change jobs, but I'm glad to be back. This is the most helpful group I've found. My pride and joy is my '73 F100 2wd with a 390. I have added chrome rims, chrome airgate, lighted running boards, cab lights, '79 grill and bumper, Edelbrock 4v. The next big task is body work and paint, but that will have to wait for the piggy bank to grow. It's good to be back, I hope I can add something usefull to the list, I know I will get alot from it.

The PO installed a power steering box off a Chevy 4x4 which mounted outside the frame rail. To perform the modification he had to cut a hole in the frame rail under the box, not good. There was a little rubbing on the pitman arm and reduced turning radius to the right but not too bad. That was until the steering arm bolt on the top of the knuckle decided to continue to break over and over again. This was with 33". So in came a 78 3/4 ton axle and 35". Cured the busted bolt but now I couldn't steer to the right worth a damn. Now all the extra stress on the hole under the box was getting too much so off it all came. My choices were to go with a crossover steering setup using 78-9 1/2 4x4 parts. The crossover design might work better with my total lift down the road to fit 36-38" tires. Second choice was to go with a 78-9 steering box from a 3/4 ton 4x4. I could keep the front to rear steering setup and have the box mounted inside the frame rail or use a 2 wheel drive box conversion to accomplish the same thing. I chose the crossover steering setup. I was looking for a softer front suspension rather than the custom springs that were rather stiff even with a winch and bumper on the front so going with the crossover steering, coil suspension similar to the 1/2 ton made sense to me. For you it might make more sense to go with the 2 wheel drive box conversion ( less expensive than 3/4 ton 4x4 box) as several other members of the list can attest to. My little steering fix has turned in to a multi year completely torn off the front end, changed my mind, building custom radius arm, thinking about going with Air springs, should I use the 3/4 ton axle or use a 1/2 ton axle with 3/4 ton parts, what the hell do I do now project. My advise is plan ahead and plan ahead some more. I thought I planned ahead but not enough it seems :( Which ever box you choose make sure your steering arm on the knuckle is in good shape. The power steering put more force on the arm than it was designed for and with the extra tire weight and traction of larger wheel & tire combos -- Don Grossman duckdon 43 GPW 63 F-100 4x4 77 F250 99 Contour ------------------------------ Date: Thu, 20 Apr 2000 11:53:43 -0400 From: Tony Marino Subject: Engine swap You'll have to swap bellhousings to a smallblock np435. They aren't hard to come by in junkyards and usually go for $50 bucks a pop around here.. 8-) You'll also need to move your motor stacions, (we are talking about the '78 4x4 right? wait, no 390's in '78... no 390's in 4x4's..... Are we talking 4x4 or 2x4???) I'm not sure on the 2 wheel drives, but the 4x4's are the same and just get relocated 2.5 inches into predrilled holes in the frame. I would think 2x4's would work the same way. I have heard swapping sides with the 2 wheel drive stancions is how you do a 300 - FE swap. Throttle linkage is also an issue (get a lockar cable system from summit for $25 bucks), along with a neat trick on how you can run the 360 radiator on the 300. (can you tell I've done this swap?) There are a lot of little simple things that have to be taken into consideration, but no big obstacle in your way except for that bellhousing really. 8-) Tony Marino redneck At 10:43 AM 4/20/00 -0500, you wrote: >Thanks for all the response on my front end question...this list is great >ain't it? > >Next question..will a 300 I6 fit on the NP 435 4spd?
