I donโt want understand the love affair with the 8.1. I had it in a 2500 Burb. Never was that impressed with it. The 6.2 in my Yukon Denali will outpull it and gets much better MPG.

Now that RAM announced they are bringing ALL HD production back to the US, "FISH" you think Ford will start making the PowerStroke Here instead of Mexico???
That get's me thinking you should be ready for a new truck by the time RAM is in production if Ford still is making the PS in Mexico you going GM or RAM???

I am not talking about stern drives. I am talking about V-Drive tow boats. My Malibu uses an LS3, which is an aluminum block. Nautique and Master Craft use the same engines as options. Mercury Marine has nothing to do with it (and, in fact is discontinuing the use of GM motors and is going with their own in-house design).

The 6.2 has been around for awhile but is not used in the HD because its not considered a heavy duty engine. (aluminum block)

I have heard this statement before, but I really question the logic of it not being a heavy duty engine.
The 6.2 is very common in boat engines now (mine has it). The surf boats spend their life turning high RPMs pushing around 10,000 pounds through the water. And will go for thousands of hours doing so.
Sounds like more than most HD trucks will ever be put through.
A 6.2 in a boat is built by Mercury. It's based on the GM design but has a cast iron block that Mercury has made specifically for the application. A boat requires a whole different design than a truck for a whole host of reasons. The 6.2 used in the 1500 is an aluminum block L86 Ecotec which has cylinder deactivation, why would you want that in a boat or heavy duty truck. GM also has/had a lot of different designs of the 6.2. LT1 and LT4 in Vettes and Camaros, LS3 crate, L94 etc.
If GM wanted, or more importantly saw the need or benefit to, they could engineer a 6.2 version for a HD truck application but they haven't. It all has to do with bottom end.
I've heard the reason it's not used on an internet forum LOL.......always true. I also sat around a campfire with the same GM transmission engineer at a rally that made the post I referenced. I tend to believe him.
