Need a little input from all you cam guru's. New engine build and I have 3 cams to choose from. Build so far, 272 bored to 292, 5cc domed pistons, G heads w/ported exhaust ports, Block & heads resurfaced just to make everything straight, Rollmaster timing chain set, 'B' intake w/600 cfm carb (may go to 3x2 later), 57 exhaust manifolds or Reds headers, T5 trans & 3.50 rear in a 57 Custom 300. I was told the compression could be close to 9.7/1. Not really looking to race it, just looking for that "saturday nite cruise" lope when you pull in somewhere. But I'm sure I'll blow the cobwebs out occasionally. Here are my choices:

Isky RPM 300 Adv Duration = 270, Duration @ 050 = 228, Lift = .448, Lobe sep = 112

Mummert Y270s Adv Duration = 272, Duration @ 050 = 224, Lift = .440, Lobe sep = 108

CompCam Adv Duration = 264in 268ex, Duration @ 050 = 234in 238ex., Lift = .528in .536ex, Lobe sep = 110

Whatever cam I run I would like to run it 2° advanced to keep the power curve on the lower rpm side. I already know that the CompCam will have to be run straight up because of piston/valve clearance. Opinions,

Thanks,   Dan
