6.2/6.5 into a 4wd?

[JohnyWard]

DOes anyone have any experience with this swap? I have seen some good 2wd conversion threads but no 4wd.

I guess I don't understand the question. What is a 6.2/6.5?

[JohnyWard]

Sorry about that, 6.2/6.5 GM diesel motors.

That's a Cummins 5.9 not a GM 6.2/6.5...at least give him OUR link.

Some other guys mentioned your Duramax swap here on the truck forum. Maybe you should PM the guy and y'all take on the challenge together online. The white truck shown in that thread is a 2wd show truck that is done VERY nicely. It's floating around here and elsewhere.

Thanks for the posts, I did find several cummins swap threads and it was quite comprehensive and had some very good stuff in them. But as it was pointed out, it wasn't really the swap I am gearing up for. I also found several threads on theses motors into 2wd trucks but they are much different from a 4wd ie the crossmember is larger, structural etc.

I heard that these motors might clear with BBC mounts. Can anyone tell me the difference in between the 2? I was under the impression that the SBC and BBC mounts were the same for the first gen blazers.

Oh geeeze...


Like a kid in school when you raise your hand 'fast' thinking you got the right answer even before you fully comprehend the question.

Sorry, was trying to send ya in the right direction.

So here's where I'm at, I am about the modifiy the factory heater box to try and pick up some extra clearance for the exhaust pipe while maintaining the function of the unit. But first I wanted to see if anyone could see any obvious flaws in my plan.

I think that there is just enough room to fit the factory core sideways, parallel to the firewall instead of protruding out from the firewall.

Here are some pictures:

So remember this:


what i was thinking was to mount the core like this:

From another direction


Its a lot of cutting and splicing, but some 1/2" aluminum angle iron on the inside and some weatherstripping for support and sealing and a new sheet meet outer with about 1" of space along the height of the core for air flow may be enough. Which give me a couple of extra inches clearance, the blue tape line is close and the turbo manifolds are not installed, but i gives an idea:



Here's my real concern, IF (and its a big if) I can get the core to fit and the cleances right, How much additional resistance to flow will forcing the air to bend 90 degrees make? Will it likely be a problem to the function of the heater?
