ASA cam base circle vs stock?? What is the ASA cam base circle, and what is the stock 1999 LS1 base circle? I have heard 1.550" for the stock LS1 cam. Is this correct? I can't find a figure for the ASA cam base circle.
I am trying to see if I can reuse my hardened 7.4" pushrods with the ASA cam if I get my heads milled .020" and use a .040" head gasket.
