Personally I think Z has done excellent job on explaining exactly how its performing. Just got be a good listener. If any of the things question here were off it wouldn’t have the bottom end he described. Thing has no mid range, its a learning curve for him and I’m sure all those possibilities he will check out. Until then we can argue now until cows come home. Well we’re are not really arguing just suggestions. My feeling he wants more power and its not going to happen with that cam and intake and some crab tuning. All the other things he can check compression, cam timing as he goes along, and secondary jetting in the carburetor. Then bingo the light will come on as to what he finds. My feelings thats a weak @ss cam for what he’s expecting. Hey it’s probably making close to 400 hp but seeing the factory show room GTO’s made 350-370 hp and were basically 13 sec cars far cry from 475-500 hp potential. It’s not going to happen with that cam. OK I will check my attitude. LOL
