Gm did have charts out before showing a 10-15% power increase just going to the 3 valve heads, and then adding 2-stage intake valve lift for better low end torque and higher horsepower.

I just never understood how they can do that. I've seen the inside of a 2v/cylinder small block, and I just couldn't see how they can do a 3V engine with the camshaft mounted inside the V.
It just seems like it would be easier just to put the camshaft over the clinder heads and make a 4v/cylinder DOHC motor.
