well i was going to build a 5.3 but now we cant get that motor... so back to the idea of building my 2001 ss m6.
my plan for the ss was prc 215 heads, not too sure on the cam yet tsp (ms3,tsunami,233/239)
bigger injectors not sure how big of ones i need 36lbs?
fast intake and now i want to do a 150 shot on top of it. are these heads good for nitrous? which cam?

thanks for any help
