if you're using a 289/302 block you could easily use an aftermarket t5 and save 30 lbs and put more hp to the rear tires (i've heard the tremecs will eat more hp, don't know about the toploader). t5 75 lbs., tko's 105 lbs.

i drive a tko600 behind a 351 with 30-hrs and it shifts better now i believe with more use. the shifting is quick 1-2-3-4, as the pedal is going in the shifter is coming out and going into the next gear by the time the pedal hits the floor at lower rpm's. going to 5th is over and up so takes more stuff. i'm using a roller pilot bearing so this might help, i also broke the tranny in with reg. synchromesh for as few easy miles as i could stand then went to pennzoil synchromesh which i read is supposed to be a preferred lube. i think the heavier gears of the tkos take a little to get used to shift wise, the t5 is supposed to be better shifting.

actually i have two different setups, one has the .64 od, the other 82. the 64 is nice to cruise at hiway but the rear gear is too small so it takes a downshift to pass. the .82 is another gear compared to the 64, with your 302 based engine i would stay with 82 od or similiar t5 or 1-1 toploader.

use a lightweight flywheel clutch assbly also, helps tremendously.
