So it seems that just about everyone thinks its a tragedy that the new LT1 out of the C7 vette isn't available for the SS. I have to admit, I kinda got caught up in the mob but after reading up on it a bit I don't see what the big fuss is about.
So it employs an afm (dod) cam which enables half of the cylinders to shut down while cruising to conserve fuel. The L76 in the g8 gt utilizes this tech but it when looking for more hp with a bigger cam this feature is typically eliminated because a non-dod cam offers better gains. Also, when the dod kicks in and cylinders shut down it causes some ill harmonics (drone) in most aftermarket exhaust systems causing frustrations. Would this just be another feature that owners would want to disable anyway?
The new LT1 also uses direct injection. DI has been around for awhile, but it seems like it still has some bugs to work out. The first thing, specifically, that comes to my mind is the issues Audi had/has with the RS4 and carbon build up. A couple local guys had major issues with carbon build-up which they had to have cleaned up which wasn't a cheap task. I think originally they had to foot the bill, but maybe Audi reimbursed them once they realized it was widespread but there still isn't a solution so now it become regular maintenance item.
Finally, with being a new engine platform, tune happy LT1 owners will have to be patient with modding their engines until vendors sort things out and develop software/parts. Tuners are already talking about the challenges the LT1 tech poses.
So I get that it's the latest and greatest but is it something we're really gonna miss having in our SS's? Even if it was available it would most certainly be a de-tuned version from the 450 hp vette engine as to not step on their toes. Maybe in a few years into production it'll make sense but the LS3 seems to be a good alternative. For now anyway. (That's assuming the LSA wouldn't be available. Cause I'd take that)
