I have a 2001 AWD LS that I like would to swap a V8 into. I also have a 1991 GMC van with a 5.0L V8. Has anyone ever done this swap? Will it work or should I find an LS?
Will this work?

I would find a 96-00 5.7L out of a Tahoe/Suburban/Silverado WAY easier than a LS swap

Thanks CopperFiremist. I'll keep that in mind. Do you know if anyone has done a 5.0L swap? I have it on hand and am parting out/junking the van it's in.
Search the site. There are a bunch of people how dropped small block v8 Chevy motors in.
There are quite a few that posted pictures and information to get mounts and to get the tranny working with carb motors systems without matching computer.
There is information on the oil pans for AWD and other stuff.

The 2 biggest issues I see will be oil pan clearance for the AWD, and the intake/aspiration. IIRC 91 V8s were TBI, the 01 4.3 wasn't. It's PROBABLY just an issue of installing the proper intake and injection system on the V8 and changing the chip, but don't quote me on that.
The LS designation on our vans designates the Luxury Sport trim level. The LS engine was never a factory option for the Astro/Safari line.
Here's the thread for my 95 V8 swap. It's long winded, but I tried to post pics, part numbers, and sources along the way.

V8 into my 95 2WD
It's 2:00 AM, and I just read through the first 10 pages in the V8 forum. Nothing I read seemed to clarify my thought process. I found a complete van at PnP toda... yesterday. It's is a 1995 G20 conversion van. PnP got it from an auction here: (expired link removed) I noticed it has TBI, my 95...

Thanks for the link Big_kid. Was your G20 a 5.0L. I have a G25 conversion van, only a G25 because it is a conversion van. Heavier suspension etc to accommodate heavier loads for travel. but has a G20 drive train. How did you get around oil pan issues and intake clearances as others have pointed out as problem points? Are you running 2 control boxes, one or the van and one for the V8?
My original post should have said " should I use a 350/5.7L V8?"
