New aluminum pushrod V10 coming from GM
from GMinsidenews.com
Escalade is planned for the V10, This seams like a logical choice for the Silverado SS too.

GM sources said the V-10s are intended for use in such vehicles as the Cadillac Escalade, an SUV, and the Escalade EXT, a sport utility truck with a cargo box at the rear. Those vehicles are available with V-8 engines only, as GM doesn't currently have a V-10 in its product line.
As power options in those vehicles, the big automaker figures the 10-cylinder units will attract more Cadillac buyers and enable the company to increase its share of the luxury truck market. As conceived, the V-10s are overhead-valve (OHV) units based on GM's existing 4.8- to 6.0-liter small-block V-8s.
The V-10 is a separate design from the Cadillac Cien V-12 concept engine introduced last year, a GM source said. That engine was based on the dual-overhead-cam Northstar V-8. The V-10 also is smaller, and considered to be more practical, than the OHV V-16 concept engine introduced early this year by GM in its experimental supercar, the Cadillac Sixteen.
The V-16 is not a viable candidate for production, GM sources said, but the DOHC V-12 is. However, the V-12, which is also all aluminum, is more likely to be used in cars than trucks and is not as close to production as the V-10, one GM source said....more

Wow, I didn't see this comming. This is great news. V10 power in the trucks...........I like the sound of that. I wonder what other applications this might have? I guess it could be for the STSv although the ohv might not cut it for people who value the placement of the cams more than output.

Re: New aluminum pushrod V10 coming from GM
Anyone remember the concept LS1 V10? 
This is going to be like that but on the LS2 level :droolsmore: I wonder if they might try fitting this into a car down the line....XLR seems to be an appropriate placement.

Re: New aluminum pushrod V10 coming from GM
This is gunna be GM's heavy duty engine, probably replacing the 8.1 in HD in trucks. GMT900 is being made for the V10
Looks like this is gunna be a truck-only engine, but ya never know. But what else would this be put in?
Big Caddy? With Caddy trying to move up market, why put a OHV "outdated" pushrod engine in there car...but they did it with the Sixteen...
Maybe a big Buick?! That would be awesome.

Re: New aluminum pushrod V10 coming from GM
Im sure this engine has evolved quite a bit since, but this LS based V-10 idea was canned way back when and the 8.1 was chosen instead . Kudos to GM , as this seems to be a pretty awesome engine . Hot Rod ( errr , I think ) did a full feature quite awhile ago about the GM V10 that coulda been in the current gen trucks .

As for the engine itself, i'm with al. I doubt we'll see this in cars, let alone a Cadillac.

Ford V10 is upgraded for this year. 3 valve head, 355hp and slightly more torque then the 8.1L

You use the same pistons, rods, main bearings, pushrods, rockers, springs, retainers, locks, head bolts, lifters, throttle body etc... and drive the amount of money required to manufacture all of the LSx family of engines down. Then... if you're smart... you take some of that money and roll it right back into engine development to pay for your high performance variants like the SS series.
My only real concern with the engine is this:
I'll bet anyone here lunch that a splayed valve engine like the Rat will out-flow an LSx based head hands down. My hope would be that Powertrain would return to looking at splayed valve designs for future LSx development specifically pertaining to high horsepower applications... unless of course the 3-valve engines are going to become a reality.
I guess if the 3-valve never happens, my ideal development of the LSx family would be:
Splayed valves
5 bolt heads w/ thicker decks
Coil-on-plug ignition
Cam phasing
Those changes right there basically make it a whole new motor.
Given all the advances since the Rat made it's debut roughly 40 years ago, I keep coming back to the idea that if the technology was applied to a Rat we'd have a killer.
Don't get me wrong... the LSx family is the best small block ever...
I just want to see the best Rat ever... it would mix the best of the new with massive displacement and an even better head design than the LSx.

The aluminum versions could enter the market with 210 pounds or more apiece of finished aluminum components, company sources said. The Detroit-based automaker doesn't currently build an engine with that much aluminum.
