OK, I know it'* not a Pontiac but please don't throw me out! I have a 93 LeSabre 3800 (L27 I think) with a 167K miles and a dying automatic. I have been offered a 94 L67 from an SSEi with a 101K and a rebuilt tranny. Question is if I convert what am I going to run into? The LeSabre didn't get the L67 so is my wiring harness go to be correct? Any infromation would be greatly appreaciated.

Thanks

Hey, neighbor. You're going to need to modify or swap the wiring harness, and you need a PCM from the donor car or another 94/95 SSEi.

www.L67swap.com may be of further assistance. And you're more than welcome to hang out here. We welcome all GM 3800'* and H/W/C/G bodies. LeSabre'* don't have a dedicated home other than here.

If your not out for power and don't car to run premium fuel. Take the L67 and swap your L27 lower intake, upper intake, fuel rail, injectors, and TB. then get a PCM made by GMTumers for the different gearing in the trans.

Engine brackets, exhaust manifolds, EGR, and harmonic balancer would also have to change. In addition to at least one trans mount.

Thank for the information - We figured we would need the harness and salvaged it, not sure if the PCM was saved ( I wasn't there to supervise). One thing I forgot to mention and probably should have, was that the L67, trany, everything was rolled out on the front carrage. Will that entire unit bolt back into my LeSabre? Thanks again for all your help.

I'm about 98% sure it will. You're dealing with an H body as well so the dimensions should be the same. I bolted a 97 subframe into a 90 Bonneville but was certain it would fit cause I had the dimensions from the service manuals.
