Not that I know a lot about diesels but I was going to put one in my 52 GMC 2.5 ton until I drove a 6.2 for a while.I got the truck cheap but it was Gutless!and hard to start in cold weather.Diesels are expensive might as well use one that has some power.




These old bolts are in my blood. Hard thing is focusing on just one.

There's better choices out there, that's for sure. The 6.2, besides being underpowered, are also bad about the heads cracking between the valves. You might consider either the 6.5 or the 6.6, or even a B4T Cummins.

Sounds like a bad idea to me too. It'll take as much work to fit as a gas V8, (a lot for that model truck) and a 6.2 or even 6.5 is nothing special....

The Cummins 4BT sounds like the best simplest swap for one of those trucks.

The GM diesels (made by Detroit Diesel) were junk. Go for a 4BT or 6BT Cummins or International DT360.

Please don't confuse the GM made V8 diesels like the 6.2 and 6.5 as being "Detroit Diesels"..... they are not.
Not arguing the junk comment, just they aren't Detroits.

I personally love the old 6.2 and 6.5's. I had one in an 85 K10. The forward band on the 700r4 got smoked after about 50K, but I treated it to TransGo shift kit and a rebuild. Wow, what a difference! If it weren't for the clatter, you wouldn't have known it was a diesel!

I'm no expert on the 6.2's or 6.5's, but from what I see folks with them in small trucks don't mind them, and folks with them in larger working trucks for the most part aren't impressed.

The way I see if if you already have one and it runs that's great, run it and have fun. But I'd never set out to find and buy one or spend much money fixing one. For sure wouldn't build a truck around one.

For sure check out www.4btswaps.com
You'll find that pretty much whatever transmission you want there is a way to make it work in most cases. Do your own research and factor the cost of making it work into the transmission cost, some options will be better than others, and which is cheaper also depends on what engine/adapters you start with.

Most importantly figure out your gearing from the start, a poorly geared conversion is a waste of time and money and can be quite disappointing.
