GEE Scooter.......your vast amount of personal HANDS-ON experience with 307s (or any engine) is based on....????

What Oldf100fordman and hambiskit said is right on.

The 307s were a good get around motor especially in something reasonably heavy. The long stroke makes for very good torque. They respond to all the hop-ups that any SBC responds to and as a rugged as the rest of the engine family. No they don't wind up like a 283, but put in a realatively heavy car with highway gears and tall tires and their no ball of fire either.

Basically waht we really need to know is what Cool Runnin has in mind for the motor before any realistic suggestions can be made.

Ahh but what do we know we've only actually build, owned and driven 307s
