72 Plaid Sub

Well, after several years of searching through the forums for invaluable information, I figured it's time to give back. I'm starting this build thread for my 1972 Suburban that I bought back in January. The plan is to restore the interior back to the original look with the correct highlander plaid and repaint the suburban in the original dark blue and white two tone. It's gonna run full Porterbuilt suspension and lay flat on the ground. Looking at LS3 or maybe a newer GM gen v motor. Here we go.

I cut an X in the top of the rivets with a cut off wheel and then drilled them with a 3/8" bit. I kept the bit sprayed with Aero Kroil and only used 2 bits to remove almost every rivet in the frame. This is not a bad way to go if you don't like using an air hammer/chisel.

Was originally going the LS engine route, but now I'm going to try an fit a 2015 Chevy L83 in the suburban. Hope I don't regret that decision. :hh::dohh:

Current situation. Modified the Porterbuilt LS mounts and got the L83 installed. Now I got to figure out the steering rack.

Really nice build. I would love to do something like this one day. Would you care to share how much $$ you dropped with Porterbuilt?

I didn't buy everything from PB directly, but I dropped about $6K with them. Picked up the narrowed PB arms from a board member here and saved about $400 off PBs price. Picked up the shocks and bags online and saved about $100.

LS swaps are bomb but are becoming a thing of the past. I will give you props for dealing with the new 5 gen :metal:

NICE!
Just saw this... Subscribed!
I'm in the process of getting an L83 out of a 2014 Tahoe myself. Planning on getting it installed on my old 1982 Silverado Stepside (Has a 6.2l Diesel in it right now!).
Keep up the good work!

Yeah, I've kept up the Instagram account a lot better than the forum. I'm getting back into it now. Should have some updates soon.

Mounting the Gen V L83 and 6L80E trans to check the fit.

Installing the Hill's Rod & Custom front inner fender wells. Delmo at Delmo's Speed hooked me up with these extreme drop inner fenders to tuck a 22" wheel and tire combo.
