10 sec. 318?

10's, why does everyone want to run 10's? I would do as Moper said. Cam, intake, headers and a gear will put the 318 in the low 14's. Work on the chassis then build a stroker 360 for it with really good heads, get some big tube headers and you'll be on your way. Either way though street friendly it won't be. But you could have a decent compromise with a mid to high 11 second car through the mufflers.
