400 horses is pretty healthy for a naturally aspirated motor. Is it a 302 or 351 you have? To me it looks like your combo will yield around 260-275hp if it's a 302, IMHO. 400 horses out of a 302 is going to have to spin around 6500rpm. Head flow will probably have to be around 280cfm on the intake side. Victor Jrs, AFR 185's, Ford Racing Z head..... Have your buddy flow test your heads when he is done. You'll know exactly how much power you can make with the flow numbers. 650 carb is perfect. Victor Jr heads with a victor jr intake and a more aggressive cam in the 560-580" lift area with around 260@.050 solid lifter....that'll hit 400! Just my two cents.....

Im a good bench racer.
