I almost went with the black paddles, but thought the polished would go better with my Billet Specialties steering wheel. You'll really like it when it's all together and tuned properly.

Well I'm going to be using a mechanical throttle linkage and ITBs so basically, no 6L80 for me, because the 6Ls need torque management. The 6 speeded 4L80 though gives me a tight ratio 6 speed so I'm happy with that direction. You basically swap out the 1st and 2nd planetaries to slightly lower ratios and to make the gear combos make sense and then use a different valve body that can apply the OD clutch in 1st and 2nd as well as 3rd, so you get 1st, 1st+OD, 2nd, 2nd+OD, 3rd, and 3rd+OD. The valve body and TCM are from PCS.
Mine is going behind a 24 valve DOHC Trailblazer straight 6 with Weber DCOE pattern throttle bodies (though I may do actual DCOE Webers at first to get things going faster).
