Engine Swap - 88 GW - 5.7 Olds diesel

[JohnIL]

The 360 in my '88 GW is telling me that it's time for a rebuild. A few years ago, I swapped an Olds 350 (5.7 liter) diesel into a gas 3/4 ton Chevy pickup with great results. I got 30+ mpg while pulling a car trailer! This experiment makes me think that a 5.7 diesel would be a good match for my GW. Has anyone every done this swap into a FSJ? Does anyone make an adapter from the Olds/Pont/Buick bellhousing to an AMC 727 trans? Or, am I just crazy for thinking about this at all? Thanks.

I thought those motors sucked. Maybe I'm missing something.

Maybe I just got lucky, but the 5.7 that I put in the 3/4 ton Chevy had gobs of torque and very good road manners.

5.7 diesels weren't know for longevity. It's based on the gas 350.

the pre 83 olds diesel had some pretty serious cylinder head and head bolt issues, as well as not being a very high output engine.

83 and up are actually pretty good all in all.. though never my first choice,

i do have one 83 up, good runner, which is going in a customer nissan, with the th200-4r and a divorced t-case.

that would be my vote also, use the BOP overdrive trans,
find or make divorced t-case...

if you had 2.72's, you could theoretically do a chevy 4x4 th400 mainshaft, in a BOP 400 case, with chevy 241 adapted onto it... (same concept goes for th350's as well)

i think the diesel would be best with OD, a lockup convertor, and 3.31's...
(they need all the help they can get)

also, the electrical systems (glow controllers, water-in-fuel) for the 5.7 are much more of a hassle than the 6.2, but if you did the swap in that pickup, you can do this too...

imho

peace,
