There is a fairly steep valley about a 1/2 hour away, hmm...... I may try another ECM, sick of sinking time and money into this "easy" swap. Before the heads cracked, this truck when running right, was intermittent before, would pull hard off the line to 5500 rpm. I was hoping for high 14's before this, now I just want something that doesn't run like sh*t. The Olds powered 4x4 was a Z71 with an open diff, who in the hell would order that? I got a good deal on a gov bomb and held up to very minor off roading and pulling the boat.Do you have any cliffs in Saskatchewan?
