GM has made a marine version of the 8100 making 430 horsepower at 5000RPM and 505 lbft of torque at 4000RPM - naturally aspirated. And just for those concerned with it's "lack of low end" - it's still making 410 lbft at 1350 RPM.
Why they don't use this in a pick up truck must have something to do with emissions, I can see no other reason they would not simply dominate Ford's V10 with it otherwise.
GM does the right thing with their gas motors. The 6.0 makes better mileage than the Ford V-10 and it is still large enough to pull all but ther heaviest loads, unlike the 5.4 V-8, which is a bit lacking in power. The 496 big block is the motor for heavy pulling when someone doesn't want a diesel. It is the only big block V-8 in a pickup, And I think that it is pretty cool. Anyway, in every test that I ever saw, it made as good of gas mileage as the Ford V-10. Right now the V-10 has a little more power, but just wait a year or two.
I have a buddy that has a 2003 GMC 2500. He never gets above 12 mpg. I have a V-10 in an '04 F-250. I always get 13 or better.
What the V-10 is a great performer. Fords V-10 gets pretty descent mileage really. I think Ford did it right. The 6.0 is too small. The 8.1 is to big and a gas guzzler. Doesnt surprise me GMs going to a V-10. Fords been way ahead off the game for years. Fords new 3v-V-10 GMs got to do something there falling behind again.

first of all the 2v ford v10 and gm 8.1 bb had similiar fuel economy not to mention the fact that the 8.1 made more power as well
gm is going to v10's not doubt mostly to comply with emissions large bore engines are difficult to be able to slide through, it will also reduce production cost as the ls1 tooling can be used.
Hp and torque figures don't really suggest gm is falling behind how ever I'm sure they will up their figures soon enough
I hope to God that you are wrong about that, and I have a feeling that you are. I absolutely, positively HATE V-10s. I don't care about how they perform or what mileage they get, I just hate them. Dodge did the right thing in getting rid of that snow flake. Now, Ford should do the same.
I agree with you here MJD. A V-8 is basically two I-4's welded together. A V-12 is two I-6's welded together. Where does that leave the V-10? I'm sure there are some fantastically engineered V-10s, but it will not be naturally balanced very well at all. When you hear I-5 it just doesn't seem right does it? I think of a V-10 in much the same way. I wonder what it would be like if they decided to go with V-12s instead.

The whole long stroke smaller bore theory about emmission is true, as Ford's engines are LEV's and GM has actually went backwards in terms of emmissions.
GM IS NOT GOING TO REPLACE THE 496 WITH A V10. It would be entirely dumb of them. If anything, GM will just drop the 496 and use the 6.0 as the largest engine offering. If anyone can find info that indicates otherwise, please post it.
Now whos right MJD. Are they or arnt they. To the poster that said fuel economy is the same for Fords V-10 and the 8.1 is mistaken. The v-10 is much better. Really the V-10 is way superior to GMs offerings. Its just right. GM must agree. The 8.1 has been plagued with piston slap and oil comnsumption problems. 1 qt every 1000 miles. Thats to steep in my book. The V-10 has had no such problems. The V-10 is an easier motor to increse power by its desighn. The 8.1 is limited. As usual Fords ahead of the game.
I don't see how an ohc, v-10, 20 or 30 valve engine is easier to hop up than a pushrod v-8 with one cam and 16 valves? As long as the heads flow, it'll go.

'Fraid so- about a 7.5L V10 to go with the new GMT900. Don't be surprised if you see a V12 version in an Escalade (or a seriously pumped-up 6.0). 5.3 will get bumped to 5.7 or so, and the 6.0 should see a significant HP increase.
I did not say that the V-10 was not a great performer, or that it made bag mileage. I simply stated that I HHHHAAAATTTTTTEEEE any V-10 ever made. No logical reason, I just plain hate V-10s.

I have to say that my experience is different, I have a 2000 Chevy silverado with the 6.0, 4L80, and 4.10 gears, it gets about 12 mpg at best. Great power for towing and smooth running, love the tow/ haul feature.
I also have a 2002 E-350, V-10, 15 passenger, 3.73 gears it gets 14 mpg, it is always at least 2 mpg better than the Chevy. I have not raced the 2 of them, but suspect that the Chevy would win, I am not dissatisfied with the V-10 power, and was pleasantly surprised that it got better mileage.
I test drove a Chevy 8.1 pickup not long ago, and didn't think it had any more power than my 6.0, not anymore "seat of the pants" power anyway.
Everyone I talk to with the 8.1 says they never see over 10 mpg.
The only thing I hate about the V-10 is when guys try to put a perfomance exhaust system on them, because they sound SICK.

I personaly love the sound.
Sounds like an F1 car, I know its different to the typical woofly trob of a V8, but thats what I like about it.
Its different...
Kind of like a Honda S600 screaming at stratospheric revs, some people may not like it, but I think it sounds fantastic...
And I would imagine the performance advantage to the 6.0l chevy would change if you had 4.10 gears in the E-350, but then the economy may go as well...
A v-10 can be naturally balanced, but the V angle has to be 36 or 72 degrees. 36 is too flat, so 72 is best. Then it's basically to inline 5s. The reason V-10 engines are usually not balanced is that manufacturers want to use the production tooling that is used for V-8 engines to produce the blocks, and set the V angle at 90 as a result.
I don't see how an ohc, v-10, 20 or 30 valve engine is easier to hop up than a pushrod v-8 with one cam and 16 valves? As long as the heads flow, it'll go.
No lifters and no pushrods means less rotating mass and more power. More valves per cylinder means more air flow equals more power.

I STILL don't see a link. Face it, it ain't gonna happen. I tried searching for info and found nothing.
