A-833 2.47 1st gear change to 3.09

Automatic is a completely different animal even with the same 1st gear ratio. My Demon had the 2.47 R in there when I bought the car, and I have no regrets swapping to the 3.09. It drives so much better.
I definitely won’t argue with you Dan, but my point was he has some problems if he can’t get an aggressive launch with a 340 and a 4 speed.

I have driven that exact combo(73 A833/3.23) but with a slant six and it would crawl out of first and do burn outs.
