K20 350 Q-jet MPG?
First off, I was on my way home with the '87 6.2 today, it started knocking badly and threw a rod.
I'm thinking of dropping a healthy 350 in it... for now at least. I have a 4 speed with 4.10 gears, the 6.2 could only pull off 13-14 MPG. I think I'd get about the same with a 350, especially with the quadrajet. Our '79 K20 350 Q jet Th400 4.10s could pull of 15-16 MPG on the highway  Not bad at all, IMOAny thoughts?
