The 350 in my '48 does about the same. Running 20/50 it will hit 40 lbs cold,
22-25 lbs running down the highway, and 5-7 lbs at idle. I thought that was not
enough, but have been told it's just fine for a stock small block. After all,
I've put over 20,000 miles on the truck in just over a year with no ill effects
on the engine.
