I have been racing 460s for about 15 years now. Currently I have a 1990 Probe with at 572 that runs 5.0s in the 1/8, and a 1969 Mustang with a 514 that runs 5.50s. I have built and put together a ton a 460 race engines over the years.

I have never built one for the street. I just bought a 44' Fifth wheel trailer so that I can haul both cars at one time. The 460 in my 87 dually is very tired.

I have a bunch of blocks, heads, cranks, etc. I also have one of the Motorsport 460 short blocks that they sold about 8 years ago. It is still new in the crate. I was thinking about using this engine with a set of open chamber heads. "The older Crate 460s had forged flat top pistons. Then use a good dual plane intake and 850 carb. I could also use a little help with cam selection for this engine.

Thanks in advance for any help and suggestions.

One more thing---Yes I would like to have a powerstoke, but with the new trailer and two cars its not in the budget for this year. Besides I really like my old beat up truck.

Building for Towing

I've got a 460 in a 1 ton that works good for towing. I built it with the 8.4:1 compression KB D dished pistons, D3VE heads and a Reed Cams cam that's a Torque master 205 at .050 on the intake and Sod Buster 210 at .050 lobe on the exhaust ground on a 112 lobe sep in on 106 I believe.

With a set of headers, Performer intake and the stock Holley carb is does pretty good on gas and it really pulls great.

With a cam this short the engine likes to have at least 89 octane gasoline so that's something to think about, I wouldn't want to be any higher on compression ratio with this camshaft.

Mine is prety much stock C9VE headed 460 in 82 Bronco with 740 carb. It has no difficulty pulling 32' travel trailer. 9.5 compression and 87 oct gets about 11 mpg. It's using CJ exhost manifolds and has 3.50 gears. The only upgrade from 69 is to dist being a duraspark.

For a 460 based combo I would use:

KB 138 pistons with the large chamber D3 castings for about 8.4 to 1 C/R at 0 deck and a comp EX 4x4 cam 210/218@ .05, .514" lift on a 111 lobe sep for carb and 114 for EFI.

performer intake with holley 750 carb 1" or 2" 4 hole spacer

curved dura spark dizzy with full advance in by 3K 14 initial 34 total.

Ported 315/185 cfm max small valve castings with upgraded single springs. This combo makes more torque and HP with ported heads.You will leave 50 HP and 30 pound feet on the table with stock heads.

headers about 1 3/4" primary shortys with 2.5" duals with an H pipe.

This combo will make about 500 pound feet of torque and 375 HP.

Another killer towing combo is:

521 stroker. 4.3" scat crank, KB 403 dished pistons for 8.5 to 1 at 0 deck

performer RPM intake with 1" spacer 4 hole.

Comp EX 4x4 cam 218/226 .514" / .524" lift ground on a 110 LSA.

ported small valve heads as in above

same headers and exhaust.

same dizzy.

same carb.

You cam make about 575 pound feet of torque and 450 HP or better. All at 4500 rpm and down.
