BBF 460 vs 503 stroker?

I was going to buy a 300 I6, but the 460 on the stand is just too tempting. I know I could have the crank turned to 2.200 offset to a 4.14 stroke and run BBC rods, but a decent Scat stroker kit is like $1,200 balanced, and will create 503" with a .030 overbore..

Any major gain with the extra 43 cubes or, would a 460 gain relativly the same? will have a 4spd, so a stall speed is no concern, but I would like it to have some go pedal right off the line... This is assuming stock D3 heads till I could afford better

Cubic inches are cubic inches, anyway you slice it, and 43 more cubes is alot. A 503 set up right will run circles around the 460. Just like the GM guys who dump there 454's for the 502. So it bears repeating the same old lines Matt. There's no replacement for displacement.

Agreed. The "bigger" Ford makes a TON of torque. My brother has a '66 Mustang coupe with one in it, at 3,200 lbs. it runs 9.80s with a mild enough build it is a good bracket engine. 11.5:1, shifts at 6.400.

The Scat crank you speak of is cast steel, not "forged". IMO, the Ford nodular crank is a better crank. The ONLY cranks better than that would be forged. We routinely offset-grind them as you speak of. Doing one right now for a "mud" truck... (:-

Go for the cubes. With stock heads your peak rpm becomes severly limited though so realize you won't gain much hp at all but your tq will go up. Your heads are restricting your hp.

Better heads would be in order eventually, but the truck has a 103.5" wheelbase and will weigh less than 3,000 lbs so it will be quick anyway.. Achieving a max hp really isn't necessary. If I could break 400 on stock heads, I'd be happy. Want more when I go to aftermkts, but that's a whole nother ballgame

Plenty easy to make 1 HP per cube with the big Ford with "pump" gas. The intake ports are actually pretty good in the 460 heads. The exhaust, however, are another story. We've made rather significant gains by welding up the floors in the exhaust ports and re-profiling them. Taking the bulk of the guide boss and AIR port also helps a bunch. The cross-section is simply too small for such a large displacement.

Comp's XE and Xtreme4x4 grinds work really well here, too. A solid roller in the 236/242 @ .050 (intake duration) makes it a mid-range monster. We set them up on the 106 int. CL per Comp's instructions.

FWIW
