It's good for torque so a 383 or 400 with low end cam that can pull stumps would be a great choice. TPI was the same way and people are still playing around with that one. I think the surprise of finding the rpm limit was big news. If you accept the limit and build accordingly then you won't be disappointed.
Oh I agree! They will do what a truck needs.

But still can't shake the 16 MPG highway with the Vortec but can hit 18+ with a TBI? I've only read that a 0411 swap with lean cruise will do 21... we'll see soon.
