Well, I'll probably regret this, but...if your throttle butterflies or your choke butterfly close all of the way, your engine won't run. There is a bypass path where your idle mix screws are. I was always taught that timing was part of a spec that included the rpm where it was to be set. Generally, you set your timing with vacuum disconnected from the distributor and all vacuum lines plugged so that there are no leaks. Every engine I can remember setting immediately gained timing and rpm as soon as the vacuum lines were hooked back up. On emission controlled systems, part of the vacuum tree's function (located in the thermostat housing) is to prevent vacuum from advancing the timing until the coolant reaches a certain temperature. Now please note that I did not suggest ported over manifold or vice versa. -- 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!!!! ------------------------------ From: "wish" <wish Date: Thu, 15 Feb 2001 22:49:20 GMT Subject: Re: Timing my motor - need advice >I tried timing my motor by vacuum and ended up with max vacuum around 16 >deg BTDC Mark, I know we've talked about this before, but if you're not pinging, I can't see why 14-16 wouldn't work with a stock compression ration on a 76 motor ...

As you change the timing you also change the mixture requirements and ported vs manifold does have a significant impact on where these adjustments should be specd at. As you say, since the throttle plate is partially open it is likely that some vacuum is reaching the vac motor on the dizzy and may move it slightly increasing the advance even with ported vac but not nearly as much as would happen with manifold vac. Typical timing at idle with manifold is 40 degrees or so and with ported roughly at initial. When I time an engine the first thing I do is play with the idle mixture balance and idle speed then check the timing. If it's way off then I make sure the vac is, indeed, working properly, reset the initial, retune the carb and check it again. As John says, the idle has to be properly adjusted first before any timing can be accurately set and the process may require at least two cycles or more to get it right because timing affects mixture requirments and mixture affects timing requirments for a smooth running engine. Rough idle is almost but not always the result of a vacuum leak but other things can do it too of course :-) Now, if you have the wrong springs in the dizzy then...............and then if........ BTW, if you can't hear the spark knock going by that wall I'd bet you are pretty safe :-) -- Happily Retired (but broke) Michigan Pot Hole Jumping, 78 Bronco Loving, Gary -- > > << BTW, the vacuum diaphram is on ported vacuum and is contributing 0 > > advance at idle. >> > > > > That is exactly the way it is supposed to work!

I would expect a cam with those specs to require a serious idle, at least 800 rpm and even then it should be loping. I had an isky cam that was what they called a 3/4 at the time and I'm sure it was in that range and that little engine loped like an angry dragon......pretty cool actually for such a small engine :-) 10:1 is on the edge but not radical I would say for today's premium. Not sure what it does in an FE but in a 460 I would expect no problems with that? With that cam you should have no spark knock at all :-) With an RV cam maybe...... That vacuum thing may be biting you more than you think too in that the carb needs a "Signal" to operate well at low rpms and vacuum is what makes it happen. At higher rpms there is enough air flow to make it work well so some tune trial and error may be needed too. What carb are you using? What tranny? Is it through a high stall converter? (if auto). -- Happily Retired (but broke) Michigan Pot Hole Jumping, 78 Bronco Loving, Gary -- > Ugh, its an FE, don't even start that thought! > > > Or you may be > >cammed up so much that's it. > > > > that's what I'm suspecting, the cam is huge, I don't have all the > specs, but > here's the basics : > > Cam Lift .296 .311 (intake/exhaust) > Valve Lift .512 .538 > SAE Duration 292/302 > 0.050 Duration 214/224 > Lobe Centers 104/120 ------------------------------ From: "Stevel" <canzus Subject: Re: Minus 40 Degrees Date: Thu, 15 Feb 2001 18:15:38 -0800 ----- Original Message ----- From: Serian <serian To: <61-79-list Sent: Thursday, 15 February, 2001 12:47 PM Subject: [61-79-list] Re: Minus 40 Degrees > ---------------------------------------------------------- > Support FTE - Check out our store: > http://www.motorhaven.com/ > ---------------------------------------------------------- > > > I have done it all too many times out in the driveway at -40 degrees > > > Celsius (damn cold!). > > > > You Canadians think that's cold?

The TDC mark should line up with the timing indicator at this point. Mine was way off. I'm not sure at what point in time it slipped, but I swear I had it timed at the 6 degree mark as suggested by the manual. When I finally checked it, the danged thing had slipped 70 degrees.

I don't know why off hand (can't think right now) but it seems like when you go to that kind of spec the timing always needs more advance. Typically higher compression (either static or dynamic, equates to absolute cylinder pressure at the top of the compression stroke) requires less advance due to faster flame propagation but at lower speeds you have lower compression with a fat cam as well as leaner mixtures so the initial needs to be higher me thinks to get it to run. I would guess that an engine with a fat cam would want more initial but narrower stops in the mechanical advance to keep the over all timing about the same so more than one thing needs to be considered when installing such a cam. The timing advance requirements cancel each other at about 3000 rpm which is why there is no more mechanical advance after that. Rpm shortens the flame burn time available so more advance is needed but richer mixture and higher compression requires less advance for the rpm so as it climbs above 3000 the compression and richness goes up to offset the rpm requirement etc...(Ok, thinking cap started working again :-)) Another thing just occured to me......some throttle plates have a hole in them for idle purposes. It allows enough air to run the engine without upsetting the "Tip In" threshhold controlled by the location of the edge of the throttle plate relative to the transition slot. I wonder if something like that would help? Another thing that may be causing some grief is a sticking secondary plate and some carbs even have adjustable secondary stops. If the secondarys are partially open, even a tiny little bit they will destroy any hope of signal to the idle circuit. I've been bitten by that one. -- Happily Retired (but broke) Michigan Pot Hole Jumping, 78 Bronco Loving, Gary -- > I would think the cam would love 12-14, and if its at 16 or so, > maybe the timing > chain moves the cam off of straight up a bit making it come in at > 16 instead > of 14 or 12 ... just a theory there. > > I finally got mine tuned up pretty good, but still can't get the > idle down where > I want it without killing it when I drop it into gear (auto).

Anyway it is a pure gear type locker with no ratchets or spragues or other clutches in it that works strictly on differnetiation between the two sides but within a limited ratio range. In a full lock turn the inside tire will turn slower than the outside by some ratio, generally less than 2:1 so if you have intermediate gear "Links" to maintain the two sides within that ratio, theoretically at least, you will have limited slip with full differentiation, the best of both worlds and quiet as well but they were very pricy last time I checked. The True-Trak claims to be equal but it acutally uses some clutching of some kind along with the gear links to do it's job. The Torsen was designed to use in the Hummer so is a strong locker where the True-Trak is generally considerd a light duty locker. Both are limited slip rather than true lockers in the 1:1 class so are prefered for such things as ice and other greasy sufaces to maintain steerage in turns etc... These, theoretically, are superior to the friction lockers due to lack of significant preload which tends to over drive the inside wheel in a turn on very slippery surfaces like Ice. Everyone I have talked to who have used them have nothing but praise for them. I was actually very impressed with the one LS I had in my van and they are also the cheapest way to lock an axle so are still high on my list as options. Those can be run front and rear of course too on the highway with no problems but again, on Ice, there will be a noticeable steerage reduction if you lock the front axle but probably not an issue anywhere else. Try a Mustang rear axle for a narrower version. They were still the full, good, strong 9" but narrower. Obviously, any Ford axle you choose will have to have the bracket removed or modified to fit the Jeep (I would think?) -- Happily Retired (but broke) Michigan Pot Hole Jumping, 78 Bronco Loving, Gary -- > Gary, > I am considering a Detroit.

Well, you have to move the throttle plates from the idle position a little in order to get the ported vacuum to engage the timing advance. If you have ported vacuum timing advance at idle on a dual diaphragm distributor, something is wrong (see over temperature diagnosis for PVS's). There should be no ported vacuum at idle because the port is above the throttle plates, which are mostly closed at idle. Manifold vacuum is from below the throttle plates or in the intake manifold, which is why you have vacuum there at idle and above idle (not WOT). The retarded side of the dual diaphragm gets vacuum at idle and above. Yes, the ported vacuum can and will overcome or at least remove (equalize) the retard vacuum. There is a system that uses an over temperature PVS (ported vacuum switch). It allows vacuum timing advance when the engine temperature gets too high. This helps cool down an engine by advancing the timing and producing higher rpms. There are more details than that, but I have written too much already. This is why you have to disconnect and plug the vacuum lines in order to set the timing. The retard side of the diaphragm is a moveable stop for the idle timing. If you leave it hooked up while setting the timing you will have way too much advance while cruising the highway. This is because you have advanced the timing at idle to overcome it. Then when the ported advance comes in just off idle, you have a spark knock under low speed acceleration under load. Disconnecting the ported vacuum line is just a safety measure. It is possible for it to be allowing some vacuum at idle (see over temperature diagnosis of PVS's), so disconnecting it removes this possibility for error because of the different types of systems out there. You have to know what the original system used is in order to diagnose or repair it correctly.

Turn the engine over till the intake opens and begins closing then slowly rotate in the direction it normally runs while holding a thin screw driver in the number one spark plug hole until you feel it stop moving upward. If you have a delicate feel you can get within 10 degrees or so that way but the proper way is to use positive piston stops and a degree wheel. If you are assuming your damper is still accurate then it is very easy, forget the screw driver and just rotate until the marks line up once the intake/compression cycle has been determined etc. as above. You rotate the "Crank" to TDC.......on the compression stroke, not the exhaust stroke. If you follow instructions above you will achieve that but be aware that many old engines have dampers that are no longer accurate and the degree wheel is the only accurate way to do it in that case. You can use the screw driver technique to verify the accuracy of the damper within 10 degrees or so at least. I've always used the damper but folks on these lists are making it clear that this is not necessarily a good idea, that is to Assume they are good. -- Happily Retired (but broke) Michigan Pot Hole Jumping, 78 Bronco Loving, Gary -- > I have the intake in place.

What this means in practical terms is that if one tire is limited to 50 ft/lbs of torque and the other one has unlimited traction potential the following would apply: (1) open diff - 100 ft/lbs would get to the ground, as the unlimited traction side would be limited to equal the other side (50+50) (2) clutch type limited slip - gets 116.6 ft lbs to the ground additional 16.6 foot-lbs provided by the limited slip (50+66.6) (2) Torsen type limited slip - gets 200 ft-lbs of torque, as Torsen allows 150 ft-lbs on traction side (50+150) (3) Locker - gets the full power of the engine to the ground (50+ whatever the engine can provide) Torsen uses binding gears rather than clutches to achieve lockup.

I am going to stick it in my 78 F-150 4x4, which has a badly smoking engine. No need to fret, however, I have a 460 out of a 73 van that will go in the 70 F-100. I have the van manifolds, and several mounts are available for the engine for around 100 bucks. My main question now is the oil pan. The pan is shot on the van engine (due to the procedure used by the junkyard we get some of our engines from.) Most things I have read state a rear sump pan is required. They cost about 100 bucks more than the front sump pans available (and I can get a front sump pan free.) The 400 now in the truck has a front sump pan. So, does anyone know if a 460 with a front sump pan will fit in a 70 2wd Ford F-100? Truck has a C-6, in case it matters.

I have a '75 F250 with a c6 and a divorced np203 t-case. When I bought the truck, I wanted to transplant the np435 w/married 205 from my '76 parts truck into it, but now, I'm beginning to change my mind. I'm starting to get used to the idea of having an automatic transmission since I don't hot dog with the truck like I used to, and I figure an automatic will be easier to tow a trailer. I also started thinking that all the 3/4 ton trucks had a divorced t-case for a reason, and my married unit wouldn't work so well. The only problem I haven't come to terms with is the 203 case. I really don't want a full time case, and having that 205 just sitting there makes it that much harder. So basically what I want to know is, does anyone know of some way to change my married 205 into a divorced 205? Obviously the input would have to be changed. Does anyone make an adapter for this?
