How large or small can this engine get? 2.5-4 liters?
I like the idea of several levels of displacement available for different brands.
A Chevy with a 2.5 and 3.6 V6,
a Pontiac with a 3 and 4L V6,
the Cadillac with a 3L, 4L, and Turbo version of the engine.
Same with V8s, 5L, 6L, and 7L, with the supercharged version for Cadillac, and a high-cost option on the others
