Whats a good cam for a mild 396. I really would like that lopey mean sound to come along with it.
My motor is out of a fairly stock 70' chevelle. Planning on rebuilding

The Comp CAm XS268S catches my eye but would it give me what I want

Lunati Hydraulic #302A7LUN....that's all you'll need for that 396.

If it's going to end up at 10.25:1, the XS268 is too small, the dynamic compression will be near 8.5...too much with iron heads....you'll have to move up to the XS274S

Charles' recommendation of the Lunati sporting 280/288 seat duration gives you 8.0:1 SPOT ON!

I've driven a 396 with that cam and 3.73s. Pulls hard.

Using the Lunati 402A2 solid, gives you 8.3:1 dynamic. Close to max with pump fuel.

If you use the small solids, you'd want CR down to 10.1, while the hydraulic mentioned would like 10.25 fine.
