I am doing a t56 build for a high horsepower application(700hp) and i have read that with "aggressive shimming" the 2 piece countershaft can be very stong, maybe not as strong as the 1 piece from the Z06 or SSR but still strong. My question is what numbers should i be shooting for on the countershaft so that it holds up the best it can?

0.002-0.004 preload

on both forward and extension or 0.00 forward shaft, 0.04 preload on extension?
