Seriously,

My Dad has a 71 on his car with a .82 back end which comes at about 3500rpm, revs till 8200rpm without much noticable drop off. Think it produces peak power about 7500rpm.

I think AJC has a 76 on his car and that spools like a T34 but I'm not sure what his limiter is.

The difference is 5mm larger diamter on the rear wheel.
