My build; 900hp, 3350lbs, been 1.240,9.02.
1965 push button 727, stock input shaft, output shaft, planet carriers, servos. Even the stock sprag for 250 passes. Never hurt it but did upgrade to the A&A unit. Aluminum drum, 5 frictions, lightened sun shell, 3.8 lever. The only part that it beats on is the front planet carrier. I should probably upgrade it to steel. It will go about 250 passes before it starts to look bad. Easy to tell, doesn't slide onto the output shaft easily. A glide will be slower but more forgiving on poor prep. Is this going to be turbo, blown, nitrous? Gets costly to go past 700hp N/A, even tougher past 800hp
