I would use the parts you have and spend any extra money on the heads and valvetrain. This build would be very similar to the 383 I had about 15 years ago. Factory cast crank, stock 400 rods w/ ARP bolts, TRW #2256 forged pistons, an old pair of Sportsman iron heads, .630 lift roller, Holley strip dominator intake, and an 850 carb. This setup went 7.90s @ 87 or so in the 1/8 in my truck, all on pump gas. And I sprayed this motor with up to a 250 shot SEVERAL times and never hurt a thing. You have to really keep an eye on your tuneup when using parts like these and trying to make good power with them.

Very well said....I agree with all points made!
