10 sec 6.1 ?

The only issue is making the power, so, what parts are needed for the 6.1 HEMI to make that power?

Cams are limited, head porting would be the next issue.

Then it's gear ratio, a good racing converter, hooking it all up to the pavement.

10 flat? I don't think so. In the 10's, I don't know.
