Don't get me wrong. Parts bin engineering is just sound practice.

What I'm saying is don't give up on the VVT/AFM too quick just because nobody makes an ECM that off-the-shelf will do what you want to do.

On my F-350 I talked the "the man" and got a one-of-a-kind maxed out MPG tune. It worked and is really driveable but diesels are pretty well sorted out factory and I only gained about 0.75 MPG from it.

I think putting a 4.8 or 5.3 LS-series engine in your old Camaro is very do-able. Add a T-56 and even with just factory ECM settings it should be an excellent setup.

A little weight reduction and cleaning up the aero and it could be a killer.

I've wondered about doing the same to my gas-hog Impala.
