I think just rebuilding 454 will make enough difference without all addon stuff i own 78 3/4 ton and only thing it won,t pull is a gas station along side but for what it does can,t complainhas more power than brakes I feel

I would consider a High torque cam. A NEW cam reguardless, at any rate. The entire valve train, cam, lifters, push rods, rocker arms and springs from the same company or matched for use with the other components. A new HIGH CAPACITY (not necessarily high pressure - your call there) oil pump and a new oil pick up assembly. Replace ALL freeze plugs in block and heads with BRASS freeze plugs. Clean all oil galleries to perfection. Port and polish the heads and use high torque headers if you want to spend the $. New fuel pump (high capacity recommended). Forged not cast pistons. Chrome plated rings, moly filled if available, stainless steel oil rings/expanders. Rebuid the carb. and install a GOOD fuel filter. Use the biggest, baddest, meanest, highest torque rated clutch and pressure plate you can find if you have a stick shift. If an auto trans, get a new/rebuilt torque converter with a stall speed at least one or two steps above stock specifications or higher. Replace your u-joints with new, high capacity or super duty types before you pull anything with the truck. After "break in" of the rebuilt engine use only synthetic oil (Mobile One is nice). If you ever have to replace the radiator stay away from "standard" and go for "super heavy duty" or "extreme service" rated radiator for extra cooling capacity. Install an oil cooler and transmission oil cooler if you don't already have them. Extra $ spent now will mean lots of $ saved later and better performance. You will like it more and more as you put lots and lots of miles on it and out pull and pass a lot of newer trucks out there.

I am not that familiar with the 454, but I have installed several low-rpm/high torque cams in my various 350's over the years and have found them to be very responsive up to a normal redline of around 5000. I wonder if Dean has any thoughts on this modification. Mine have always been Competition Cams, but I'm sure that other brands are just as good. The cam is relatively inexpensive and probably should be replaced with an overhaul anyway, so your incremental cash outlay should not be very great.

Good point! As long as you are very careful about the exact cam you pick and the relationship to other modifications, a high torque cam can be very helpful. The best approach is to spec out all the modifications you are going to make, right down to the part numbers. Then the last vendor you talk to is the cam vendor (Comp Cams is a great outfit) and tell them exactly what changes you are making and how the engine will be used. They do this a hundred times day and have a wealth of knowledge. Don't be surprised if they recommend a split duration cam. Big blocks respond to them very well. I can't overemphasize how important it is to use all the valve train parts (cam, lifters, pushrods) from the same vendor and follow their installation instructions to the letter.

I've been rebuilding big blocks for a long time and here's what I'd do. Do a stock rebuild. Use a dual-plane manifold with 750 cfm carb, no larger. I'm partial to Holley but any decent Q-Jet will work well. Put small tube headers on it. Run a 2.5" dual exhaust with a crossover pipe. Run a Link HEI ignition system. They will curve it for you. Put a Modine 4 tube radiator in it. Have fun!

Dean - Have you ever built any big block Fords? I am getting ready to do my 460 and was wondering if there are any special tricks of the trade for this motor. It is in a 1 ton 4x4 that pulls trailers and a few stumps here and there.
Thanks!

Sorry Craig, I'm strictly a Chevy guy. But I'll bet there are plenty of Ford folks out there who can help you.

Come on guys, help Craig out!

Have rebuilt quite a few of the 429-460 Fords and the most important thing to get more low and mid range grunt out of them is to advance the camshaft timing 4 degrees. The easiest and best way to do this is to get an aftermarket chain and sprocket set that has 3 keyways in the crank sprocket for 4 degrees retard, 0 degrees, or 4 degrees advance which is what you want to use.

Jon - Thanks for the info. I am getting ready to take the block to the machine shop and I am also getting ready to start buying parts for the motor. I will try your suggestion of advance timing because I am mainly looking for torque out of the motor. Thanks again!

Edelbrock and Weiand both make excellent dual-plane intakes.

I have been thinking about a rebuild on mine, has 147,000 but still pretty strong. I have a '89 and it has the factory throttle body fuel injection and gets pretty good mileage. I keep my cooling system clean and keep the electric fan working and haven't had a problem with overheating, but I don't have the air conditioning working, just suffer through the heat and humidity (East Tx).
