Ridefast: Did you have the conversion done? Actually I might suggest dropping an 8.1 with the 4L85 behind it.

But your dumping 15 grand into a build. Gonna take you 375 fills with saving 40 bucks a fill up to get your invesment back.


Personally your going to see maybe 13-14 Towing and 15-17 Highway. So really your probably going to end up losing money. Just doesnt make sense to me. Why not just buy a diesel, not if you go to trade or sell it, who would want it.
Were talking about ROI on this forum where we spend stupid money on boats, fuel, vehicles, etc....?

The power difference will be huge!

The 6.0 in your hummer is a turd and the 4L80 tranny has a ridiculous 1st gear ratio. You will smile every time you stomp on it! And towing will be much easier.

Sounds like it will be a unique and cool setup. I look forward to the completed reports.

I wonder if they would put a Duramax, or better yet a 7.3L PSD in my 2-door Tahoe for me.

I have seen Cummins diesels in Broncos so a Dmax might work. If not you can always drop a 4bt in it.
