C-20 to K-20 body swap - The 1947 - Present Chevrolet & GMC Truck Message Board Network

bowtieguy79 · 07-08-2010, 08:39 AM

Thought I would share my current project, that I finally started. Have had the parts for over a year.

Started out with this.

And this past Tuesday started the frame swap. Enjoy

Now just to find time to get the drive train installed.
Drive train will be 5.3/4L60E/NP241 ( NP241 is from a 90 burban )

It looks pretty easy in pics doesn't it! Proves that you can do just about anything with a good cherry picker!

I did a C10 to C20 body swap several years ago with a cherry picker also

By MYSELF! On a Patio behind my house. How redneck is that!! Now, I have a 24X30 shop for my second body swap coming up this winter. This time it'll be a breeze

I did the body swap on my 67 C10 to K10 conversion with the cherry picker bolted into the bed of my K20 in my back yard by myself. Works pretty good, just wish I had a 2-car+ garage to work in to finish the job.

bowtieguy79 · 09-14-2010, 10:25 PM

Got it home, and started doing some more prep work.
Trying to see if I can retain the AC location from the LS engine. Made my own mounts, seems to be working ok. Need to adjust the motor mounts at the frame, it doesn't want to sit down in the mounts like it should.

nice swap!
looks good with the hubcaps,,real sleeper

Davidmichael · 09-15-2010, 08:12 PM

awesome job so far!

87 V20 Scottsdale · 09-15-2010, 09:12 PM

As the truck sits now it has 16" stock wheels with 305-75-16's

bowtieguy79 · 09-24-2010, 09:42 PM

It currently has the engine and trans between the frame rails as well as the double din Delco CD player installed. Making progress slow but sure!

Davidmichael · 09-24-2010, 09:53 PM

I always wondered what one of those factory CD players would look like installed.

palposity · 09-24-2010, 09:54 PM

So did you have to install a body lift to accommodate for the difference in the 2wd and 4wd tranny hump in the cab?

Nope, I should have added these pics in

Still need to do a little metal work, but this should work.... gotta love plasma cutters!

3r!c84 · 09-24-2010, 10:45 PM

Got it. I had to swap out the tranny hump in my truck too.

nope just a little 5.3L It was cheap and available. Wanted to run a 6.0 but there is always next time right!

48cj2a · 09-27-2010, 01:08 PM

Looking good - You have me about convinced to quit looking for a diesel replacement.

Need to stop by and see this some time and pick your brain.

Since I'm still picking parts would I be better off picking up a TBI harness on the firewall side since mine is a diesel to make this hook up easier?

What Tranny and T/C you going to use? Got the 400/208 now.

68 TT · 09-27-2010, 03:21 PM

The 5.3 is no slouch plus they are easy to come by if you blow one up. Not so with a 6.0 engine.

With a cam, headers and a good tune a 5.3 will make over 360 hp to the rear wheels.

Add in a 70 mm turbo and an intercooler with a Z06 Vette cam and it will make low 600's to the rear wheels with a stock bottom end and unported heads.

48cj2a · 09-28-2010, 03:02 PM

Any cross member issues?

Define issues? All I have to do is re-drill all four holes. Other wise the mount is the same as the 4L60E adapter as well as a 700R4.

I heave ho'd the transfer case in tonight. Then had to pull it back down once I saw the gasket laying on the bench.... DOH... So on the second attempt its mounted. I was able to measure for shafts tonight. Plan to visit a buddy's stash and see if I can find a close fit.

And for the record, YES the NP241(27spline) mounts directly to the tail end of the 4L60E with no issues!

Did you use the 700R4/NP241 adapter then too?
