New L96 RPO...
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???

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