SBC w/TKO600

[Marty G Cars]

I just picked up my 2nd Camaro (68 RS/SS, NOM 350, Saginaw 4 sp) a couple of weeks ago and I am planning to do a mild PT upgrade. My CC5S TKO600 will be in on Monday. Here are a few questions:

What would be the best (deal/price/warranty) non LS SBC crate motor to install? I am shooting for 400-500hp. I don't care if it's a 350, 383 or even larger. I also want to set it up as a pump gas daily driver w/a preference for vacuum boosted brakes and carburetor.



I will be upgrading the rear to a 12 bolt (3.73) and it looks like Moser has the best deal/reputation unless someone has better experience elsewhere.

Also has anyone used a Classic Auto Air system?

Thanks
Marty
