suggestions for my 340?

you don't know what gears you have not sure about the engine-- but you want to go faster. That is one vague & expensive statement.

This made me laugh. Anyway I'll bet you have 355 ish gears. You have to factor in at least 500rpm of converter slip when calculating with an auto trans.

yip. I just bought the car a few days before posting. guess I should have torn it down to bare metal before asking any questions? Im looking for guidelines of good parts/bad parts etc. This isnt the first time I've built a car. Just the first time a mopar small block car. rather not waste my money on crap parts or useless ones. Thanks for the attitude.

so a 3.55 gear rear end will have me revving at around 3700 rpm at ~67mph? interesting.
