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:


The 455 ready to be mated to the frame:


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.

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.

Some pictures of the motor and the truck as it is now:



Wheeltubs in the box, and oak plywood stained grey to look a bit aged.
















Wheels powdercoated I have 15x10's for the back and 15x8 for the front, both with a lot of reverse:

My dad's 33 Dodge coupe. It was originally rodded in the 70's, with a 302 Ford and C4. Brought it up from a family friend in Montana almost 2 years ago.

Nice any picks on the rad mount...looks good are ya gonna leave it in original patina

[05snopro440]

Yes, the patina is staying the way it is. Don't have any pics on how I mounted the rad. It had to be kicked out at the bottom to clear the steering box. I wanted as big a rad as possible though to keep the 455 cool, and we did some unique fabrication to get the rad mounted in there to that it works. The bottom mount is a strap of 2" flat iron that is welded to the original rad support, and bolts to the flange on the rad. The top is aluminum straps that keep the rad in place to the top rad support.

Definitely a cool project, I think it looks good just like that!

Great project. You really nailed the stance, looks dead on. And I gotta love the big Buick mill.
