Looking to buy/build 500-600 fwhp 360

car looks good , what is the purpose of the car , drag strip street or road course ?
if you are just looking for 500+ hp go for a built 360 with nitrous
It's mostly street with occasional drag racing. I'm kinda leaning toward a stout 360 with 200 hp nitrous shot. Everybody loves the 408 stroker, but I think my limit with this engine and car is about 600 hp. Might as well keep it tame at 400 street hp with a nitrous option. I'm going with all forged internals and aluminum heads with a roller cam. Might do EFI.
