The noise Police don't care for "run it dry", if your cam was 10 or so degrees bigger cut on a 110 LSA I would be checking plugs for water.

I don't, but what are you comparing them to ? they still seem small for a 509 that may get a supercharger. There again, that's only my opinion.

The dyno testing was back in 2004 and 2006, the BB2 Xtras made 1372 HP @ 6200, 1188 Torque @ 4400 at 15 psi if memory serves me correctly. The Big Dukes were making 1325 HP @ 5000 when exhaust...

I believe the Chevrolet crate 572 is 4.560 x 4.375, that's why I asked. I think the 4.5 crank is better for a boat and I think it would like a little more cam than a shorter stroke, but it's only my...

What RPM range are you looking for ? I'm not an engine builder, I don't sell camshafts but I've tried a few. I never saw much from retarding the cam except it made the motor lazy.
