Made some progress this week on Recon Rovers D1 6.2L install. This truck has Toyota 3rds. The reinforcing rib on the oil pan looks like it will foul the diff. I expect I have some grinding to do. There is a half inch clearance between the PS pump and the steering box. The alternator is in light contact with the hood reinforcement. I expect the hood reinforcement will get an "adjustment" of some type. So far all the hardware has gone in nicely. I'm using a bare LT230 case at the moment as I have a 1.003:1 LT230 under construction for this car, but it's not ready yet. The engine was installed first and the transmission and transfercase were put in from the bottom on a transmission jack. The engine balances well and the gearboxes can be removed for service without any unusual difficulty. The truck is running 35" tires with 4.56:1 diff gears. I'm expecting to have to swap in some 4:11 third members, as I expect it will be geared too low. I intend to try and rework the wiring harnass myself instead of sending it out. The 6.2 is out of a 2013 Silverado pickup (I think). The intake manifold that I was supplied is GM P/N 12602477. It is set up for the same MAP sensor as the truck intake and also uses the short injectors. The injectors from the pickup are the right length, but they are too small a diameter and are a loose fit in the intake....so I'm about to get an education on GM fuel injectors.
