What is the compression ratio?

Also. How stock are we talking? Passenger car stock?

Depending on what all else you plan, your best bet would be to stick with 112° lobe separation and mild lift with longest possible duration.

I really like the Comp Cams Xtreme Marine XM270H for situations such as yours. It's a proven off the shelf stick with a pretty good track record.

Hope that helps.
