I am sure my 383 would want more timing on pump gas if it were not pulling around a 7,000 lbs Express van with a 4L85E and only a 3.73 gear. 6L90E swap coming soon though. I bet it wants a little more timing when the engine is not under as much load.

It really depends on the setup. I have seen LT1 builds want as much as 38* on pump gas at 12:1 compression.
