Re: 72 GMC Longbed Duramax Swap

OK!
so, second weekend in the bag!

first thing,
because the donor truck had been wrecked, the Oil tube had a small crack in it. First we had to braze the little hole.

We put up the duramax mounting plates, and polyurethane motor mounts.

Once we had the mounts on, just to check, we sat the engine in on the v8 towers. Obviously "NoGo." The Aluminum section of the oil pan was sitting on the crossmember.

We moved it around, and raised it. Figured we needed about an 1 and 3/4 inch spacer to get everything clear.

Luckily, my dad had a trailing arm from a peterbuilt that he sold about 20 years ago. It was closer to 1 and 7/8. but it works!

with the spacers, we mounted it into the stock "v8" mounting holes.
