For 2010, GM is showing a new RPO "L96".... 6.0L, 9.6:1 CR, iron block kind of as a garden variety 364.... I know the LY6 has L92 rectangle port heads, but so far, I have'nt found out if this L96 is using them, or the LQ4/9 cathedrals. I'd hate to pass up a gem in the junkyard. Anybody???

I would suspect with the HP ratings that it is a cathedral port head. But, I have not been able to find a definitive answer on the GM site.

The L96 uses the same part number cyl head as the LS3, so it has rectangle ports.

J-Rod

ok, so it is a VVT 6.0L with an iron block with L92 heads.

So, yes, it would be a good find for someone looking to do a 6.0L with L92 heads...

Hmmm, the L96 and LY6 have the same Peak torque @ the same RPM. The Horsepower is very similar as well, could that be just a slightly different cam?

Would you mind telling me what resource you used to determine this? It would be very helpful for me in the future.

Well I just scored a L96 and 6L90E Complete with only 2 miles on the motor..

Once I get a chance to look at it close I"ll try to post some part numbers...

Did you get that from Schaums? I thought about buying that motor.

I'm pretty sure the L96 is the Flex Fuel version of the LY6.

My L76 motor is an aluminum block 6L with L92 heads from an 07 Vortec-Max otioned truck. I wonder (besides block material) what the differences are

2 miles? the hell happened to that truck?

This is interesting, seems like a budget build dream, especially for boost..

The L76 in the pickups has VVT like the LY6 and L96, but unlike the LY6 & L96 it also has AFM (active fuel management) aka DOD (displacement on demand).

The l96's will replace the ly6's. The only difference between the two is that the l96's are e85 ready.

Yeah I got it from Schaums.. I made an offer, he mad a counter offer, I made another offer 1/2 the difference and the next morning I got an email that they accepted it.. I'm so stoked... I talked to the guy there to get some background.. I said really only 2 miles on that motor.. He said yeah, it was damaged in transport on the back half of the van..

I have been searching for all the info I can get for upgrades and I guess it is still that new.. I hope this goes a long way to putting my 70 Monte Carlo into the 20th century..

It was damaged in transport from the plant.. I asked the guy.. Ok how is it that the motor only has 2 miles on it.. he said the back of the van got tore up and they scraped the whole thing... I am NEVER this lucky like this.. I just hope I can pull some ponies out of it with usual bolt on items

I was thinking an LS3 Intake, cam and headers... I'm stuck on the headers.. I am thinking the mid length headers not long or shorties.. Not sure how the length plays into things..

Thats what Schram's and Norstram's do, they are official GM dismantlers. They always tear apart new vehicle that got damaged somehow before making it to the dealerships.

I bought a 5 mile engine from Nordstrams and the pistons were still shinny, you couldnt even barely tell the engine had ever been run!

Dumb Question but was is Schaum's

Id go longtubes or keep the manifolds. Unless what youre putting it in comes with tri ys a lot and you can change the flange. The manifold they come with is good, and length makes all the difference.

Congrats! Do you mind sharing what you paid for it? I went back and forth with them a few rounds on price early in the auction, but they wouldn't budge at the time. That thing was super clean. What are you putting it in?
