Okay so i have a 350 that i bored out to a 357, i have Edelbrock performer rpm heads, 1.5 rocker rollers, and a lot more but to much to type. i want to buy a cam that will thump and sound great but i canto go much higher than a .500 lift because it will be my street car and the heads i have can only handle a .550 lift. I can go a little higher but anyway if someone could give me some ideas on a good cam to use?
