I am thinking real hard about a new ZZ502 for my 1967 Nova, but before I take the plunge I was wondering if anyone could give me an ideal what it sounds like? I mean does it have a little bit of a muscle car sounding cam or is it just sound very stockish. My 454 has a comp cam with .595 lift 248 duration at .050 and has a mean idle.
So if somemone out ther has a ZZ502 please let me know what you think of its idle sound.
Thanks
