I started reading the specs and thought ..... sounds like the motor in my Mustang..

My motor is 12.5:1 and the cam is smaller.. If I remember right it has .650 lift and more like 263/258 duration @ 50 etc -- and requires 110 octane... It DOES NOT like to be lugged....like anything below about 3000 rpm it's not real happy... but is wonderful on the road course.

The problem with going to a smaller cam is that you may actually end up raising the cylinder pressure. I seriously doubt you could ever get it down to pump gas level with 13:1 CR pistons.
