Swapping L86 6.2 8l90e into 72 k10

Nice build.

Can you share on what you had to do for a shifter? Also what wiring harness and ecu/tcu set up did you go with?

Thanks!

The shifter for the 8l90e was believe it or not the easiest thing of all. The shift arm the the turbo 350 bolted on the 8l90 with no modifications at all. The frame pivot for the linkage needed one of the two bolts moved a little, it would depend on where exactly the engine ended up. The original column shifter needed to be adjusted slightly and it works fine.

I am using the stock ecm and tcm. My wiring harness was reworked by Mitch at Swaptime. Unfortunately, i would hesitate to recommend him. Way to long to do, and way to hard to get in touch with him. If i was doing it again, i would do the harness myself, and either do the programming myself or send it to Speartech.

Most excellent. Thank you for sharing. When I am ignorant, I like to over complicate things. I really helps to see what others have done to solve the things that come up.

I'm doing the same swap in a 72 C10, and am just about to the point of hooking up the shifter. Glad to hear it was a breeze! That's one less thing to rack my brain over. Thanks!

Well done! It is looking like a clean install. Thank you for sharing.
