I have an '82 GS with a Bridge Ported 12a, Holly 465 w/ intake from RB, RB SP header, RB exhaust, grounding kit, MSD Blaster 2's, Magnacore 10mm wires, etc. etc. and when i take her out to flog her, i'll get between 5 and 8 mpg, but cruising on the freeway i'm getting ~24mpg.

my stock 81 gets decent mpg on the freeway cruising like around 26-28, but when stop and go driving ie around town and what not, i only get like 10-15 depending on how im driving
