Hello all, I have just recently started debating about what engine to swap into my 85 K5 and I am pretty set on a Duramax. I have been reading all that I can but I cant find very much trans/tcase info. I want an automatic and a good low geared tcase. Any ideas? What tranny would hold up to the hp and torque of the Duramax? This is going to be my DD and wheeling rig. It will be linked front and rear with a Dana 60 front and 14bolt full floater rear. Thanks!
