i'll try in order....
- Going from 2.76 to 3.73 will be a huge help.... in the 1/4. Not for cruising on the highway, it will sound like your in 2nd gear.
- My average gain on "home-porting" heads is approx. 4 tenths
- Who said the factory tins are .028 thick? I'd say .018 is closer.
- Quit with your "paper" dyno. Cutting heads helps low end torque, so stop with the paper 4 hp thingy you got going on... LOL. That being said, I wouldn't cut the 302's.
I forgot the purpose of your car, low E.T. or nice highway cruiser.... just back to thinking about your gears.....
