Actually there are several questions to this post.

Since this is my 1st Mopar with a 383/4bbl to be exact (no tach yet) in a stock 64 Fury I'm wondering what to expect for a safe or typical RPM redline. 5000 was it for stock small block chevy's I grew up with and I'm figuring 5000 is about it for a stock 383 as well. Is this right?

I was thinking of changing the 3.23 rearend for a lower ratio to add some zip but after reading several threads on this forum I think I'm going about it all wrong. Looks like I should be trying to increase the HP and Torq before messing with the rearend ratios.

Any suggestions for bolt on items that will increase the power and what kind of increases can I expect. I don't want to break this engine either as it is the original to the car, but I also starting to question the real value of that too. Seems nobody wants stock and 440/426's seem to be the big draw on these cars.

Thanks,

Butch
