LBZ blow by?
I did a boost test leak and identified the issue. The hex screw on the wcfab y bridge pipe had backed out some and that’s what the sounds was. I tightened it back up and it’s good to go now. Also replaced all my trans lines- talk about a messy job. Amazon was the same price on the lines as rock... -

The problem was eight cut wires in the harness under the driver side fender near the bottom of the windshield wiper fluid tank. I believe the cause was when the motor was pulled the cab was removed and set down on the wires. -

Attempting to program TCM with Tech2. Calibrations out of date
I can’t find an A40 anywhere. This son of a bitch on eBay sold me an A40 and it was a T14a. He took eight days to ship then send that. Highly frustrated. Truck is just sitting. I guess I’ll call the dealer tommrow and see if they sell the A40.- 06DDLBZ

Wrecked on Christmas, Flooded....Need some help
I think I want to build this motor. I know I might can get away with getting a 12 second stock truck but with my luck its just not worth it to me do this twice. Having the donor motor out I would really want to do pistons, rods, lml crank, AF cam and head studs and rebuild the transmission. I...- 06DDLBZ
