350-400hp budget build 360 ideas???

Yeah, that budget for me is very limited. That's why I said EQ Magnums. They'll support that power level and can be gotten for $600/pr or so. The rockers are stock Magnum, any boneyard or probably members here have a spare set. You'll need oil-thru pushrods and a lifter that has the oil feed in the top. Most mopar stuff do now anyway but technically they are for AMCs. I think by tring to rebuild the short, or the heads, you'll wade thru that $2K before you get a running engine out of it. I figured $700 for fresh heads and the rockers, the rest can go into headers, exhaust, gaskets, paint, belts, hoses, etc etc etc...
