Is this engine builder nuts?

If your still going with the 318 build I'd stick with something the would work with 3.23:1 or 3.55:1 and stock stall. 9:1 CR, 650 and headers and something like comps xe262h and for heads if you go with stock would get you around 300 hp or you could go with 340/360 or one of the aftermarket magnum heads like EQ which would add 30 or so hp.
