still not decided on camshaft. i am rebuilding my engine. it is a 95 trans am i am having it bored 30 over and will have for the most part stock heads and intake besides matching the ports to the gasket. i was looking at the whole LT4 kit with cam lifters rockers ect. how does this cam sound.i want a little more lopey sound without having to replace the heads or anything.will it have a good gain over a stock cam? or would i be better off with something like the cc305 or the cc503?
