Duramax Swap

Hi All,

My apologies if this has been covered, I've searched this forum and didn't find much.
Has anyone done, or considered a duramax swap into a gmt400?

I started thinking about this today as I've been searching for a 1 ton CC to buy since i've outgrown my 5.7 EC.
I happened across a 97 SRW CC with a dead 6.5l (shocking!) for sale.
If a complete truck -engine can be had for cheap enough, I figure it may be worth it to swap in the newer engine to save the cost of buying a newer truck, but still have the benefit of the power and gas mileage in a 6.6l duramax.

Another benefit to me would be smog exemption in CA since 97 and older Diesels don't require smog.

Any thoughts?
Would you consider doing this swap?

Ferminator on DieselPlace has done it. He has a lot of money into it. Go check out his thread.

I also think he's on here but hasn't posted much;



Personally, as cool as a Duramax OBS sounds, it'd be hard to beat a simple 12 Valve build.

This. Duramax are cool, but Cummins is the way to go. Easier, cheaper, and a much more reliable engine.

garret kwist on facebook has done it, he had an entire donor truck and grafted most of the cluster and column into his build

Don't know if you do Instagram or not and this user may be on this site but guys name is @gkchev on there and he has a ridiculously sick dmax build

Truck trend did this swap. Check out their article.

Rereading this thread now I think we're talking about the same guy.

Are you guys talking about a white RCSB? It's got a NBS rear bumper and tons of color matched stuff? If you are I sorta remember it, sick looking truck, y'all should post pics

yes we are talking about the same guy and yes it is that one.
