Well here goes.

I’ve spent hours searching the web, and can’t find anyone who has gone this route, so I’m here to ask a question that may or may not sound stupid.

I have an 07’ Yukon Denali XL with a 6.2 L92. It’s mated to a 6L80, and AWD.

It has 207,000 miles. Still runs strong but a bit clanky when cold. (Common for these).

I have a hard time believing this engine will last more than 50,000 more miles. I could be wrong, but it just doesn’t seem as smooth as other Chevy v8s I’ve owned, and from hours of reading I’m not the only one who feels this way.

I also know from my hours of reading, that the intake manifold is not the same, and that this throttle is electronically controlled, which means you need a bunch of adapters IF swapping from 5.7, 6.0, etc, to 6.2, but I’ve yet to see someone do it the other way.

So to cut to the point, what would I be looking at to replace the 6.2 with a 6.0? Obviously I’d want said 6.0 to make 380hp like the current motor, but that’s not really that hard to achieve with a 6.0.

Thanks all, and I apologize if this is a dumb question, but our family loves his vehicle but I can’t justify spending the 6 or 7k it costs for a crate L92, or having it rebuilt, and I’d just like to be prepared if the situation ever presents itself.

I would have to think that the associated costs of finding a suitable 6.0 and all of the necessary parts and possible headaches would rival that of simply rebuilding your 6.2 that you say really has no issues other than perceived longevity at its current mileage.

to answer your question: any Gen 4 6.0 will be a direct swap. Most of the Gen 4 6.0's have the rectangle port heads and they will use the exact same intake manifold as your 6.2. The Gen 4's will be from 2007-2014 for Yukons, but you could get one from a Van, truck, or SUV etc. Depending on which 6.0 you get it will be down on HP due to lower compression, 12 ci smaller (364 vs 376) and slightly smaller cam. To make up the HP you could go with a slightly bigger cam (even a stock 6.2 cam) and some flat top pistons to get the compression back up.

Consider sending out oil samples of the engine oil and transmission oil for analysis to Blackstone Labs. Then you will know the condition of your engine.

It will cost less to freshen it up. Put in new rings and bearings, lifters and trays and such, send out the heads to be rebuilt with new valve springs and seals and keep on truckin'.

So if I have a 6.0 lq4 bottom end, I could use my l94 heads, intake and cam?
