What I have so far.

-Box stock FMS Aluminum SCJ heads
-Core d9 block, crank and Double dot rods out of 94' F-250
-.030 over h418cp pistons 22cc dish
-Holley 3310 750 carb

The 460 will be for my 5000 lbs 1979 F-150 shot box 4x4. I do not tow, off road or race the truck, it's mainly used for hauling light loads, back up rig, and street cruiser. I intend to remove the 351m and t-18 I currently have (and hate) and replace them with the 460/ZF 5 speed combo.

At this point what would I need to round out my engine? I'm not dead set on the pistons I have, (most of this is just stuff that I've had from other projects, other than the heads) but would like to use my heads and core short block that I will have rebuilt and balanced. What would be a good choice in intake, cam, etc. Carb too Small? Strokers as of today are out of budget. Thanks for any advice. Goal 475-525hp?

I believe the heads you intend to use, requires a special piston. It will have a valve releaf in a different location.

^^ Yea, that I know, I'll need to check and fly cut or get the correct piston.

I have seen the HP builds, just throwing this out for my specific vehicle and application.
