Slow 71 GMC Build - The 1947 - Present Chevrolet & GMC Truck Message Board Network

lukefalls · 05-10-2011, 07:05 PM

I have this build listed on both Pirate4x4 and ColoradoK5, but I wanted to post here to get some more feed back. I've had this truck for nearly 10 years. I've neglected it and hacked it. Time to fix it.

The plan is for a 4x4 long travel, go-fast rock crawler, cruiser. That a lot to expect for a one truck. I am still looking for an L92 or L9H (I'd settle for an L76). I want to run a 6L90e with a Atlas 4spd or a Stak 3spd. It'll be orange, might steal Nibs' orange. The body lift is gone! It'll run Method or WER racing wheels with 37" Toyo MTs. I don't even want to think about how much the King C/Os and bypass shocks are going to cost.

I have a '79 Ford Dana 60 for the front. I'll get 3.73 with a Detroit. It now has new alloy shafts, 35 spline outter shafts, and Warn Premium hubs. It also has WFO Concepts double high steer arms. This probably won't work with the amount of wheel travel it'll have. We'll see. I have everything for the 3 link + pan hard front. Its not done yet because I want to mock up the engine and make sure it'll work. The 4 link rear is in place, I just need to finish my trailing arms. The entire cage needs to be built.

Here is everything I've done so far. I am finishing up the driver's side door and rocker right now. Its not going well, but more about that later.

Now my problem:
I cannot get my driver's door to line up...with anything. I can get any one side to line up with adjoining metal and still open and close smooth. If I want three sides to line up, the door closes smooth, but damn near take a crowbar to open.

I cannot all sides of the door to line up. The reason that I started working on the door today is becuase I've been uphappy with the LMC rocker pannle. I figured that I'd make sure the door/cab/fender was where I want them. Then cut, twist, stretch, etc the rocker to where it lined up really nice.

Help...please. Feedback is always welcome. Good and bad. I'm learning as I go and will not claim to be an expert on anything.

Thanks. I'm going to try to ship up the front of the cab and see how that works out. I'll keep you posted.

Lookin good!

lukefalls · 07-28-2011, 01:30 AM

Well, I got the body mount/cab issue sorted out. I just needed to adjust the bushings. Thank for the help on that.

Interior Towing of Fairbanks helped me a ton! The loaned me a smoked 5.3 to use for mock-up. Other than the hole in the block and oil pan leaking oil everywhere, its working perfect.

I am finding that the stock exhaust manifolds are too wide and hitting the frame. I'll look into Camaro manifolds. I've heard that they're narrower. Any input on this?

I am using a large bushing and sleeve as a motor mount. That'll get it a bit lower in the frame than the stock motor mount will. Its also easier to fab that way. Again, any input?

All that I got done tonight is to hang the engine and make plates for the block. Hopefully tomorrow, I'll have it bolted in with a new cross member.

Time for pics...

seriously, use a dead blow on the bottom of the door. the problem is the rockers are curved and most of the doors out there werent shaped very well to fit the rockers. ive never seen one that lined up perfectly. i spent literally weeks lining up my rocker and still had to use a dead blow to drive the door in on both bottom corners just slightly.

lukefalls · 07-28-2011, 03:04 AM

'92, I'm about ready to do that. I'll post photos when I do. If it doesn't go well, I'll post pics of myself taking a dead-blow to the entire thing.

lukefalls · 07-28-2011, 11:52 PM

I'm a bit disappointed with myself. I spent all day making sure that the engine was exactly where I wanted it. I measured about 50 times and got everything perfect. I really took time to make the brackets so that I won't make the "ghetto-fab" thread.

Once everything was built and lined-up, I tacked it. Then removed the engine and measured again. Then I welded everything in for good.

Ultimately, everything is okay. I was really hoping for great. I need to finish up the engine mounts with the boxed sides (with speed holes of course). I'm also going to build a cross member. Now that I have the engine in place, I can build the 3 link front and know that my links won't hit the exhaust or oil pan.

I talked to Kevin at Pacific Fab today. He was very helpful...so much so that I think that I'm going to pony up a buy an engine from him. I'd recommend Pac Fab to anyone looking for an LSx. Like I said, Kevin was super helpful.

Now, for the pics. FLAME ON:beer:

Now that I got the engine in place, I was able to put the Ford Dana 60 in the truck. I mocked up the upper link for the 3 link. I will have definitely 7" of up travel. There is 8" until the upper link hits the frame, but I wanted at last an 1" for safety. I may need more. We'll see.

As promised...speed holes!

lukefalls · 11-11-2011, 01:34 AM

I might as well post an update.

I've been insanely busy with work the last few months. I did finish the 3 link front. There is going to be just enough room for the exhaust.

Billhilly · 11-11-2011, 05:19 AM

Great work!

lukefalls · 11-11-2011, 09:40 PM

Thanks for the input. I'll be on hold for a while. My wife is due with our son in January.

Right now, family is first. I'll make sure that I get updates loaded as I make them.

Expect to see the details on an L96 swap and full cage.

Nice truck and build, I know how it feels to have a cool rock crawler, beat her up (while having fun) and then realize that she deserves to look nice. Glad to see more K series being re-done.

lukefalls · 11-13-2011, 02:03 AM

72LSK10,
I think that I've seen your truck. I used to live in Huntington Beach. I thought that I used to see it around Long Beach. Would have been about 8 years ago.

I've definitely beat it up. Now its time to fix it...right.
