49 ls1

So I've been prodded to start a build thread on my newest acquisition. 49 3600 Chevy 5 window. I was given this truck when I was 11 years old, and until the last year or so have been steadily pimping the parts off of it for other projects. However, last time I was home, it didn't look near as far gone as I had remembered (or maybe every joker on craigslist seems to think that their rusty farm truck that has been sitting in a field for 30 years is worth $2500). So I decided to drag it home and see what could be done with it.

Sorry, no before pics.

Re: 49 ls1

I started with a half ton frame that already had a 71 Camaro stub on it. I found it at auction for $200. After taking careful measurements I decided it was done pretty decently (I'll be adding some gussets and fish plates just for GP) and would make a good platform for my new shop rig. Heres some pics.

Re: 49 ls1

I've been wrestling with direction for this project. I've picked up a 5.3L from a wrecked 2005 Suburban, and a 4L80E 2wd trans from a 2000 truck. I'm leaning towards "Hot Rod Flatz" firemist Fathom Green, mild bodywork, air bags, custom built radius arm independent rear suspension, 17x8 steelie wheels with 55 chevy pickup dog-dishes, 55 Chevy pickup dashboard, and maybe a few other items. Here's the color, interior will be 2 tone, green and beige.

I also picked up a 55 truck dash from Jim Carter here in KC, figured to play with that a little bit and see if I couldn't get it to look ok in there.

Re: 49 ls1

So I wound up cutting the ends of the 55 dash off, then integrating them into the doors, so that when you close them the dash becomes wrap around. I think it looks kinda trick, but there's a helluva lot of metalwork left to do!

Re: 49 ls1

So here's my 5.3L... 98,000 miles, gave $350 for it. It's a 2005 drive by wire, which I am converting to a 2001 PCM and drive by cable setup. Looked kind of nasty when I picked it up, but turned out to be in real nice shape inside! Final pics are all buttoned up with LS6 cam and fresh paint.

Re: 49 ls1

Next on the list was a better radiator option. I wound up ordering a 19x22 double pass crossflow radiator from Speedway (for like $110!) with pass side inlet and outlet (perfect for an LS motor). I bought a junk core support to cut up from Jim Carters, and got to work. I needed to get the radiator high enough to clear the Camaro power steering box, while giving myself enough room for efan setup in front of the motor.

Re: 49 ls1

capped the bottom in 18ga steel bent to capture the rubber rad isolators from mid 80's Ford POS cars (Left upper from 4 different cars was the right width!) and mocked it up for trial fitment. Clears the power steering box by about 3/4"...

That's about it for now, hoping to get the motor mounts mocked up once the core support brackets are complete, maybe by the end of the weekend?

Re: 49 ls1

Thanks Daze... It just seemed like it was in better shape than all the stuff I was finding for sale! What you see is what you get though. I have no headlight stuff, no windows, a bent to hell grill, no box, no rear fenders... etc. They're out there though.

Re: 49 ls1

I love '49s. My formerly best friend got one when we were in the 7th grade. Did a little body work to it, threw it on an s10 frame and let it sit since. Sometimes I wonder if he truly appreciates the things he has. Good looking truck, looking forward to following this build.

Re: 49 ls1

Nice project and I like the dash as it is the same one I used in mine. What is your plan for the gauge cluster? I'm using a flamed one from EBAY for something different than the stock one.

Re: 49 ls1

Thank you all for the interest... This will hopefully be my showcase truck.

Alaska gasser, I was planning on using the stock '55 cluster. Going for a certain look, custom, but not too much bling. I found a nice speedo converter that will allow the stock speedo to work with the VSS on the 4L80E.

Low elco, Craigslist bro... They're out there. I picked that one up from Leavenworth, KS.

I'm hoping to have this one in shape for the Midwest All Truck Nats next year... Would look cool towing my V8 Lawnmower!

Re: 49 ls1

Finally got my core support located so I can remove the fenders for engine mockup! I'm hoping to have motor mounts built by the end of the weekend, then on to some bodywork.

Re: 49 ls1

So I decided to mock up the 5.3 in the engine bay to see where I was at, and where I'd have to cut. I mounted it about 2 inches higher than I would have for a 350, so I can use the stock pan. Since this truck will get bagged, I don't want anything hanging below that crossmember.

Initially I had about 3.5" of clearance between the wp pulley and the rad. I'm looking for about 5". Rather than buy a different accessory drive, I decided a 2" recessed firewall was a good option. So I made some rough cuts, bolted on the trans, and blocked it in position.

Re: 49 ls1

Once I was happy with the positioning of the motor, I started to put together some motor mounts. The last shot is with the intake in position (It kinda fits perfect in the factory 6 banger recession).

Re: 49 ls1

Once I had the mounts made, I strengthened them with some 1/4 wall tube, and started banging out a new firewall. I want this one to be smooth, so I cut the factory one completely out, saved and re-used the 6 cyl recession (and moved it down about 1.5"), and cut 18ga. sheet to fit. It's just sheetmetal screwed for now, but I'll be welding it in, and re-bracing the backside tomorrow.

Hopefully this weekend I can get the cab off, and build the trans mount.
