It wan't happen any time soon, I just rebuilt my 235 and I'm waiting for the Vermont Snow to melt before I put it back in my 59 fleetside. But just for laughs...and because I'm curious... Is there such a thing as a diesel engine out there that would go in and let me use the same transmission? I love the 3 speed, and I don't want to change that. Also, I'm admittedly and amature mechenic, and I would have to pay somebody to do any kind of fabrication and welding and such. Is there an engine that would drop in pretty easily? I want to know because some friends of mine work for greasecar ( www.greasecar.com...cool site), and I'd love to drive my truck without the hit in the wallet every time I fill it up. But I'm also kind of just fantasizing. Anybody out there know? | | | | | Joined: Aug 2001 Posts: 78 Wrench Fetcher | | Wrench Fetcher Joined: Aug 2001 Posts: 78 | Please don't take this too seriously as I have major doubts about my own knowleadge. First of all, a 265/283 was an option for your truck right? Therefore a small block swap should be a no brainer. Second, didn't chevy make a 350ci diesel that was based on the gas-powered small block? It might be worth looking into, but I haven't heard the best comments about this 350 diesel. I'm sure someone will correct me if I'm wrong.

Haven't heard much good about it, in fact I remember reading in car magazines of the time that folks were converting the engine from diesel to gas (was apparently a bit of a dog). To pull off this swap, you'd need a bellhousing adapter plate from Chevy pattern to B.O.P. (Buick, Olds, Pontiac) bellhousing. you'd also have to fab up side engine mounts, a crossmember, etc. A lot of work, but it WOULD be different! Regards, Wannabe

The older models were lacking power. I would be concerned about the added weight. The original exhaust would have to be changed to bigger diameter and extra cooling would need to be considered. I would think the right gearing and proper camshaft selection for a gas motor would be a better way to go. Joe | | |

Maybe for just driving around, but if I had a diesel I would be pulling something! | | | | | Joined: Feb 2002 Posts: 20 Member | | Member Joined: Feb 2002 Posts: 20 | I'm a pretty serious GM fan, and do like the torque and the smell of diesel smoke...but if I were contemplating a swap it wouldn't be GM- they just never figured that part out. Maybe a Cummings turbo (6 cyl- like REAL TRUCKS  .

I asked on The Diesel Page if the 5 speed in my '93 would hold up to a diesel, and popular opinion was no. So the 3 speed probably won't work. I often thought about using a diesel, cause that is what I am trained to work on!!
