so i have a 74 350 in my camaro that i will be putting in. i want to get a new camshaft because i heard that the 74 engine camshaft restricts or is low to lower the emissions. i have no idea where or what to get. i am only using the camaro to drive around town. its not gonna see alot of track, but i would like some more performance. i would love that burble sound that the older muscle cars get. but shoot me some ideas because i dont know where to start.
