SBC cam difference?
I`ve got a GMPP 290hp 350 in my el camino. for those not familiar, rated at 8.5:1 but closer to 8:1, dished pistons, 993 casting heads if I remember correctly and the L82 cam which is the old 350hp 350 cam. It runs decent enough and I`ll fine tune it before making any changes but how better or worse would it run with the Crane 274HO6? I`m actually doing a deal for a summit version of that cam now so it`s coming. Any idea of how it will change the power band? Right now it has a Weiand Stealth, Holley 670cfm Street Avenger, HEI, headers, flows,and a 4spd. Will probably get 3.73`s pretty soon as well. I`m going to dial it in with the L82 cam and see what I can get from it before I change it but I`m curious what you guys think about the power difference.
