Heads and cam for na/ nitrous 416 - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I’ve got a 416 with ported stock heads and a 244/260 cam 11.7 compression that made 510/474. When the original owner had the motor built it served as his dd so street manners came into play for me it’s a racecar so street manners mean nothing to me. I would like to go to a more aggressive cam and heads to match the cam and cut back on the spray if possible and still make my goal of 9.99. The car has a built 6l80 and stock posi mod rear diff that will stay until they break, then a built 4l80 and a zl1 rear diff will go in. I’m considering the gpi max package but would like to hear about any proven combos and would make a solid improvement for the dollar.

Definately aftermarket castings like PRC or small bore LS7. Id leave the cam alone depending on the rest of the specs. I wouldnt mess with a 4L80 and just run a th400 especially since its a racecar. I daily mine even.
