I live in a very hilly area. Just moved here about a year ago. So glad I have an 8 now in my Model A. It never would have made it on these hills. That being said, I would like to maintain a more constant mph over the hills if possible. I also have some hot rod blood in me and vintage speed equipment is not ugly, in my opinion.

The engine is .030 over, was a very good running engine. Saw the car with this engine in it before it was pulled to build a street rod. Stock cam, stock intake with an English stromberg. Bubbas crab distributor, iron heads and headers I built.

End goal, have it stay in its power band the whole time. It tends to fall on its face in third if I stretch her legs. Also maintain speed over hills are rather tall.
