Nice set up for the T-case. I went with NV4500 and Atlas 4.

A new headboard was installed on the truck bed, then the bed was test fit to the cab and frame.

Re: 1972 c10 conversion to a LSA powered k20 build thread

While it is still at this stage, you guys misplaced the "super" emblem on the driver's side. Common mistake seen on restored trucks. It always goes under the Cheyenne portion of the emblems on both sides, not more on the right hand side. Just thought I'd help ya out ahead of paint. Trevor

Is it going to be stock height or is there plans for a lift? And if lifted what tires/ wheels will you guys be using.

The truck will be getting a 4" lift kit, and I believe the tires are 285/75/18...they are at the tire shop right now, so I can't look...but I do know they are 34" tall.

Put in the new 4" lift springs, then mocked up the motor and transmission.

The engine compartment was then mocked up with the radiators, fans, and other misc components for clearance and mounting points. The guys also fabricated a custom engine cradle for the LSA.

Re: 1972 c10 conversion to a LSA powered k20 build thread

Maybe I don't understand. The LSA is just like any of the other LSX blocks right? How are you mounting the engine thought you needed a modified crossmember

Reviving an old thread here. Beautiful build, and nice attention to detail. What heat exchanger and rad did you use and is it working well to keep the LSA cool?

Ok though maybe you found a top secret way. This amongst other things is why I'm leaning away from an lsx swap. Wish I had your tools and skills. That is gunna be one sweet ride

Thanks a lot guys...the truck is really coming along nice.

Here we cleaned up the rest of the frame to get it ready for sand blasting, and fabricated mounts for the gas tank.

It's a TANKS inc gas tank, but we had to do a good amount of modifying to mount it.
