gh0st, I don't know if I can go as specific as south indiana

but I was thinking maybe a sticky including vendors of both engines and aftermarket parts for the CA.
And Cosmo, I really don't know what the max boost a stock CA can handle. There are so many variables...These are old engines, and it will vary drastically... You'd be better off making a thread (rather than a sticky) asking that question if you'd like some more input!
good ideas, keep 'em coming!
