I don't understand why some are saying the engines will be maxed out. Until GM says they are going to be aiming for 100 hp/L with these engines, the potential will still be there. And I just don't see them doing that. They'll still be large displacement truck engines at heart. It won't be 500hp 3.9L DOHC VVT DI V8s with a 10k rpm redline (too much hyperbole? meh). They'll need to retain all their exisiting qualities. The ability to mod these engines is directly related to one of the other advantages to ths SBC: low cost. Cheapest way for an automaker to make an engine powerful is to make it large displacement. And GM will want these engines to be about as cheap as possible because they'll sell about a million of them each and every year. Saving a few hundred bucks per engine will be utterly massive to GM.

The next generation of GM engines will incorporate DI and VVT. I heard they are going to accomplish this with 4v heads but the engines will still be pushrod motors. Possibly going to use cam in cam technology or run 2 cams keeping them both inside the block.
