I currently am finishing up (finally, still another week to go I think) installing my offy 3x1 steup w/ Langdon's headers. After this, and redoing all the brakes, and adding a power-unit, I was planning on swapping the Powerglide that's in there now, for a built TH350.
How much of a performance increase will this give me?
Info if needed:
72' Nova w/ 250cid
Mostly street driven, with a little highway.
