86 GMC, Porterbuilt Mild front and rear

Figured I would finally post what I have been working on. The story goes that I bought my 86 GMC while on leave in 2009. It sat in my fathers garage for the next year until I could come back and get it. When I did get back, I did a mild build on it which included a Mcgaughy's 4/6 drop with big brakes, 20/22" Coy C5's, and a 5.3L/4L60E swap. I drove daily for a few months before getting deployed again and then it sat once at my fathers house. Fast forward to late 2012 and a separation from the Corps and it's build time! Name:  001.jpg

So for the second go around, I decided to run a Porterbuilt Mild dropmember front and rear. I built a cammed 6.0 LQ9, Performabuilt Stage 2 trans, 3.73 gears with eaton tru trac. I figured I would post some of the issues I have run into as well, mainly steering linkage and headers.

Fabbed ECM mount. Headers are Hedman Muscle rod. I had to notch the dropmember to get the correct angles for the steering. The drivers side header has the front tube rerouted to clear the joints.

Nice, I have the same year Chevy. I'm looking to drop in an Eaton True Trac as well, let me know how easy it is to install and how you like it!

Re: 86 GMC, Porterbuilt Mild front and rear

I haven't had a chance to use it yet. The installation was pretty straight forward. I used a nitro gear rebuild kit and it's the stock 10 bolt. You will need a press for the bearings and an in/lb torque wrench.

Re: 86 GMC, Porterbuilt Mild front and rear

Thanks! Honestly, if I were to do it again, I would just go with the extreme version. It would be less fab and fitment issues.

As soon as I can get the exhaust hooked back up, I'll get a video of it running.

Re: 86 GMC, Porterbuilt Mild front and rear

I sent you a PM, and was wondering if you could get a picture and maybe some info on how you modified the inner frame support for the steering shaft clearance? I'm at that point and it would be a great help.

Thanks, Wade

Re: 86 GMC, Porterbuilt Mild front and rear

I'm at a crossroads right now and need opinions. Should I shave and repaint the firewall? Or, make a panel to resemble the a/c heater and put some undercoating back to look kinds stock?

Re: 86 GMC, Porterbuilt Mild front and rear

Depends on the look your going for. I've redone so many things I've lost count. Thinking I'd be happy with it and not dough what I really wanted to do in the first place. If you like the look of a smooth newly painted firewall, do it now, or you'll be redoin it later. It's gonna be super nice either way!

Re: 86 GMC, Porterbuilt Mild front and rear

If it works for you I would smooth it, looks so much better.

Re: 86 GMC, Porterbuilt Mild front and rear

That is what I was leaning toward. I'd hate to pull the front end off to do it later. Thanks guys.
