07CTS-V

iTrader: (6)

I'm looking to run my LSX 427 with 9:1 CR naturally aspirated this summer until I build a twin turbo setup this fall at which time I'll be swapping heads and cam to a more turbo friendly setup. I have an '07 CTS-V with PRC ported and polished LS3 heads and a Tony Mamo ported FAST102. I'm looking for suggestions for a NA cam with the 9:1 CR. I don't care about drive ability, I just want the nastiest sounding cam with lots of Hp up top.

My previous setup was a NA 418 LS3 with 11:1 CR that put down 513/478 to the tires. Here's what it sounded like with a 242/252, .612/.622 113LSA.

You're going to want something pretty small with a tight lsa to get as much cylinder pressure as possible with that low CR.
