I'm looking to put an LT1 or preferrably LS1 in my 1993 Chevy G20 Van, but can't find any information at all on the conversion. It currently has a 4.3 non Vortec TBI and 4L60E tranny. I've done a search in the forum and on the web and can only find info for the Astro van - nothing for the G vans.

My friend was telling me if I went with the LT1 I'd have to offset the motor mounts and notch the frame or buy a corvette bracket kit at the very least. I was wondering if there might be any like this involved with the LS1 conversion as well...

If anyone has any info on this I would greatly appreciate it!

Thanks,

99bravada.

The LT1 swap shouldn't be all that hard. Should be just a matter of tracking down the v8 parts. G20's came from the factory with small blocks (which isn't a LT1, but is at least similar). I think you could even get the big block. However, I'm not all that familiar with GM vans, so maybe you couldn't get a 1 ton.

The LS1 swap is much closer to uncharted territory. Good luck with that. I don't have any advice for you there.

I've seen a full size chevy Van with a LS1 and a six speed. The engine looked lost in the van. This thing was really neat. It was used to pull a race car with and the owner said that it got 17/18 mpg pulling a loaded trailer.

I also am looking to do a LS type Vortec 5.3 into van. I guess I will need pan and mount adapters and hope the vortec truck acc brackets work?
Any one done a swap?
