1946 gmc

[05snopro440]

I figured it was time to make a build thread for my 46 GMC. It will be road-ready in the spring, but I've already got a year of progress. Unfortunately I have a bunch of pictures that I don't have uploaded yet, and don't have a lot of detailed photos, but I'll post what I have for now anyways.

It's on an 85 S-10 regular cab longbox frame. The 46 is a 3/4 ton, so we shortened the box 9" to make it into a shortbox and get the wheels placed where I wanted them in the wheelwells. Driveline is a 74 Buick 455 with a turbo 400, Mercury Mountaineer Aluminum Driveshaft and the S-10 rear with 3.42 gears. The 455 has an Edelbrock performer intake, Comp 268H cam, and a Demon 650 CFM carb. I used the brake boosterand it's inner brace (firewall to dash) from the S-10, as well as the pedals, steering column, and seat. It's got a Vintage Air GEN II Heater, Painless harness, and Northern Aluminum rad (direct fit for a Hemi Cuda).

Here's the frame ready to go after getting everything squared away:

Frame and driveline all sorted out. We had to make our own motor mounts for the frame side because I didn't have them from the Buick. Lots of work but worked out really well.

Cab finally set on the frame after several times on and off and trimming:

Then we had to patch up the driver's rear fender (a part of it was missing) and we built a roll pan between the fenders, and put 50 pontiac LED taillights in the pan. I did my best to make the patina on the roll pan blend with the truck.
