1987 GMC V1500 Sierra Classic LS swap/build

[NastyBuzzard]

y5 its my pride that is hurt... Plus it had all original sheetmetal... I feel so bad that I hurt it.

Updates: Got a little farther tonight. It is about time to pull out the drivetrain. Need a buyer for this low mile 92 tbi engine that was rebuilt .030 over w/ flat top pistons and vortec roller cam setup. The 700r4 too was rebuilt less than 5k miles ago with corvette servo and trans go shift kit.

Anyways:







So ready for the new setup!



Got to get the old out first and clean everything up!

Any recommendations for replacing all the body mounts? Polyeurethane or oem rubber? I need a kit that supplies new hardware.

Got the driver's fender, hood, windshield, roof (right at the windshield but windshield frame is still straight), driver's door, and driver's bed side. Looks like I'm going to be dusting off my body work skills, haha. Stuff happens, glad to see you're still plugging along.

I feel like you can get her back right!!

Yeah I'm still going at it, found some motivation. Wearing me down though, only time I am able to get out there is after the wife and kid go to bed. Still worth it!

Got a little done tonight. Unhooked all wiring from engine/trans/tcase. Got exhaust all disconnected. Front driveshaft is unhooked as well. Really hoping to get it snatched out tomorrow. Fingers crossed.

If you are using all the wiring and the gauges for the '01 why not use the fuel module from the '01 as well, already has the right pump and fuel level sender. I believe you can modify your current tank or a 20 gal to accept it with:

Mrwhitels1 did it on his blazer (now on his K10)

I would love to do that! The 01 pump assy is really deep b/c the 01 tank is really deep, it has a spring mechanism on it that makes it go to the bottom of the tank.

If I can find more details on how to do that, it is exactly what I will do. It is the best way to go about it in my opinion.

[NastyBuzzard]

Just some more updates..

Wiring harness removed from the 87.





My mess:



01 donors rad may be trashed...



Transfer cases adapters are a tad different!





Tried to seperate the 01 donors wiring a little. Makie it a little easier to manuever and run. Seperated into engine wiring, fuse panel wiring, and interior wiring.

Since the module has it's own bucket you don't need an EFI tank. Sure you can find non EFI 20 gal for pretty cheap.

Thanks!!

So you are saying I need a non baffled tank instead of the baffled 87 tank I have now?

I maybe could try and track down a 20 gal tank or just maybe buy a new one.

Also the artic blaze thread guy is using a blazer tank, which has the hole for the pump assy like in the middle.

These damn side saddle tank has the hole for pump assy near the edge of the hump..

I think it may still work though... Not sure.

You can still use your current tank. Just saw you were thinking about moving up to a 20 gal tank and figured if you went this route you don't need a baffled tank. It being in the middle isn't a big deal, ideally you want it mounted in the deepest part of the tank which is where I believe the current sending unit in the tank is mounted. If you are worried about the module being too tall, from what I can tell a majority of modern GM vehicles have roughly the same design for the fuel modules with varying heights. If you have a pick and pull need by you could find one closer to your current tanks height.

Yes I eventually want to go to a 20 gal tank.

Thats a great idea about pull a part. Unfortunately, I don't have any that are close by. Could go to Azone or Advanced and just get them to show me a crap ton of the ones they have in stock.

Not sure what vehicles to check though? Maybe a van or impala or something?

I would say 20 gal. longbed tank for your truck would work.

I'll work on locating one. I could probably find a decent used one that isn't baffled for pretty cheap. It is trying to find a baffled one that is difficult.

[Flatpat]

I suppose you could have them show different ones that they have then see if a junkyard or craigslist has one. From what I've seen, you want the module to be about an inch (uncompressed) taller than the tank. Then the springs when compressed make sure it doesn't move.

Possible to modify the "bucket"? Change or cut springs?

Module? Are you talking abou the fuel pump assembly?

[Flatpat]

The most popular module I'm seeing used in swaps is the 99-02 LS1 F-body module. Also the Pontiac modules are popular, grand prix, GTO, etc..

Here's a good read on how this guy did his.

Very nice!! Thanks! Only difference is he extended and I may need to shorten...

Although without the baffles in the tank I may not need to shorten too much...

Gonna try and track down a 20 gal carb tank.

[Flatpat]

No problem, I'm looking at doing the same thing to the dual tanks in my K30 for a 8.1 swap when I get back so I had been looking around for info. It'll be cool to see how it works out for you.

I will take plenty of pics! I need to find a huge hole saw!

[NastyBuzzard]

Still wondering how this is gonna swap in.



Got these bad boys in today!! Got them on sale too!



My 87s trans is getting ready to say bye bye tomorrow.. Gonna swap it for something special but don't want to jinx it!



Next big step is to wire wheel/clean frame and paint it chassis paint.

[NastyBuzzard]

700R4 is gone! Traded it for this:









Details:
2002 6.0 LQ4 167k miles
Came with everything minus exhaust manifolds, power steering pump & bracket, ac compressor and alternator w/ bracket.

Story goes; friend wanted to swap in brand new engine b/c original one had very low oil pressure. Bouncing from 0-20 psi at idle.

Previous owner said he drove truck on the trailer, brought it home, drove it off trailer, swapped engines and he got to keep the old one. Said he was gonna stroke it for his race truck. Low oil pressure but only had valve chatter no knocking.

I checked oil after I got it unloaded and is about 2-2.5 qts low. Gonna let this one sit on my stand and maybe rebuild it once I sell my 350 TBI. Who knows.

Still planning to swap the 4.8 into my 87, mostly b/c I know it ran decent right before I pulled it.

[y5mgisi]

Nice trade!

[Hankster]

Good score! I say put in a new PCV valve and a oil change and that motor is probably fine.
