Re: '06 Tremec T-56 into '68 GMC C-15 w/ 600HP BBC 427 questions...
Any reason you aren’t looking at the TKO-600? Seems like the perfect fit for you, gets you the 4 speed muncie style with an added OD. Won’t require as much modification as a t56 I swapped from a muncie to tko and was able to reuse a lot
