I'm pretty sure they've worked out a way to keep AFM from hurting the power numbers now because I believe AFM, VVT, and DI will be on all V8s from now on.

If you go to Chevrolet.com and look at the new Corvete and look at the LT1 it advertises a "trio of features" as standard on the new LT1; VVT, DI, and the dreaded AFM.

 

Yes, that's pretty much what I said.

There's also a chance that the AFM does still affect output and GM will come out with a new successor to the LS7, without AFM, and even more power.

 

With 454 cubes! - yeah a guy can dream can't he?

 

I've been hoping for a truck version of the LS7 minus the Titanium parts since it was introduced. That would let us forgive GM for canceling the 8.1L Big Block.

Anybody going to miss the Vortec name for the truck engines?

 

When comparing the new 5.3 to the Ford 5.0, one has to remember that the 5.0 does not have DI yet. Thus, when they upgrade the engine, it will see pretty good FI increases.

However, for now, the 5.3 one-ups the 5.0.

 

I wonder? I don't think DI is going to be some sort of shot in the arm people make it out to be based on prior statements by Ford unless they were just trying to disarm the competition? I guess we will see though and Ford might pleasantly surprise people when they install DI.

Frankly though I'd rather see a tall deck coyote that can at least displace another liter or so.
