furweln84 wrotedid you get a noticable difference with the tfi upgrade? i am hoping it will help reach my mildly built 304's potential.
For the 258-6 it's kick-ass! :lo1l:
For the 8's, I'll have to wait and see personally, I'm just now building and AMC V-8:? But the 4-bolt main Chebby I had in the 75-CJ5 - I couldn't tell, (but then again in a short WB, I could get wheelies in 3 gears, but never had the gonads to open it up all the way :shock: .30 over, torker, cam, 750 double pump, ported/polished, mongo headers and I think I had a muffler, but couldn't tell :wink: )
But I've heard that it smoothes out a lot of the rough idle and pulls well thru the RPM range. :idea:
