Mark, Cupp has answers to all those questions. Dyno comparisons, on track back to back, every trans. and rear gear combination you can think of. We have MIR again on Monday and he will be beating the tar out of the green bean again. ------ I'm going to quit parking beside him----------Danny

Seems to me that the 409 340 horse engine of 1963-65 had a BIG 4 jet on it. 394 Olds motors and the big Buicks got it as well. Heard of a fellow putting one on a 283-220 horse and getting a BIG quantum jump in horsepower with it. I had a 65 Impala SS convertible with a 409 340 horse and a 4 speed, but I ran an AFB on it,since they were easier to maintain. That car was a real road monster with the 3.31 gears, and it would tow about anything. Nothing like torque.
