Wow Chris, that is great power for such a relatively low rpm!
eperky: I like hydraulics for most purposes. Don't have to set lash often.
If you want a 500+ hp mud engine, I suggest you go to the link I gave in an earlier post. I don't do mud, so I would hate to recommend anything to you. There are a lot of factors involved that might work better for pavement drags than bogs, and vice-versa.

 

You can recurve your distributor yourself. You can modify it to your needs for free. All you need to know is at www.reincarnation-sutomotive.com/duraspark distributor recurve instructions.

 

but how often do you need to keep your motor at 5000 rpm or better on the street.only if youre looking for trouble.the car is just to nice for the track.but anyway than kyou guys for all the responses , i always love a good talk with fellow gearheads

 

your stock heads are 94 cc+-here are some cheap and easy build tips for a 460, use a set of 88 up fuel injected 460 pistons, very nearly f/t, you can also use the fi heads with some port work, they will run circles around even a dove head, set the cam timing 2* advanced, performer package works well but intake won't match ports on heads if you use the fi heads, put a good oilpump & drive in

 

from what i've read and heard the fuelie heads and the doves with similar port work have pretty close numbers but may be stretching things a little saying they'll(fuelies)will run circles around the dove heads. heres a link with the flow #'s on the heads http://460ford.com/viewtopic.php?t=15276

 

maybe flowise they are close, velocity and swirl, not even comparable, also the fuelie heads have a better designed chamber that is a little bigger so with a ft piston compression will stay under 10:1, with the doves compression can hit 11+ in a hurry which limits amount of timing and kills power, todays gas sure can't keep up with the old engines, I burn either propane, good for 13.5:1, or methanol , unlimited squeeze

 

i sure wish they would make a intake to match up with efi heads.but i want to stay carbed,unless i can find a complete doner truck, ive looked at several 460 motors for sale but they all have been 88 and up.i want a good street setup for this motor.i plan on starting on it in feb,cant wait thanx for the tips fordsrgrt and 1evilcrewcab.everone has been very helpful

 

i say scrap the 460 build and go with a 302. its much lighter weight and the shorter stroke will give you more low end power for that big truck! just my 2$

 

you can use the factory fi intake with a carb, you only have to plug the injector ports or leave the injectors in and buy the adapter to bolt a carb onto that intake, i left the injectors in, used them to inject water/methanol mix on my 13:1 propane 498 cube 385

 

Shorter stroke = more low end power?
Bob, I suggest you do a bit more research... longer stroke always = more low end torque, and, in a F250, the 250 lb weight penalty isn't exactly going to be noticed nearly as much as the loss of power and torque would be...
One can quite easily build a 400hp/500 ft/lb 460 and have a perfectly drivable engine without breaking the bank, a 302, not so much....
My 557, well, not so much either.... LOL

 

you said your engine was an 86? Those heads are the large chamber smog heads, it would be wise to run a dove-c head from a pre 72 engine, that way you wont have the added expence of milling down the pedestals for screw in studs,if your going to use a factory head there are large bumps cast in the exhaust port short turn, take a die grinder and cut those down to blend with the surrounding port area this is reportedly good for a quick 20 horses, as far as 550 horses that is as easy as falling off a log! I run a 385 series in my 87 f-250 street modified pulling truck, we have to run cast iron intakes and are limited to .490 lift cams and flat top pistons. I run a zero decked 429 block with a 72 460 crank, eagle rods, and scj heads with a solid .489 cam that is 256/264 at .50 duration. zero deck with a flat top piston and 72cc heads is 12.48 to one, and even with just the scj cast iron manifold this motor combo makes 611 horsepower and 625 lb/ft with peak hp at 6100 rpm at the crankshaft. the only streetability problems that I have is 6.00 a gal for 114 and not smokin the hides at every stop sign, but then again I hve a 03 superduty to get back and forth to town with.

 

well i found a set of heads off of a 72 460 out of a lincoln i believe will these be the better heads that i need?

 

they should be, check to see that the casting # is not d3ve, as I believe these heads lack the quench that you will be looking for.c8ve or dove will be your best bet because they had factory installed screw in studs.

 

make sure they aren't d2ve heads, those are the WORST 385 head you could get, same chamber design as 351M/400, very detonation prone

 

my bad typo on my part i meant d2ve thanks for the correction.
