This may be a silly question – I have not seen it discussed yet (probably because nobody wants to talk about it).
Does anybody out there with the ZZ502 know what kind of gas mileage you get with a behemoth like that? I am considering putting one in the 72’ with a Tremec 5-speed and 3:08 gears. Well, at least a few co-workers are trying to talk me out of the full-up LS2 and T-56 conversion and they have me thinking. The ZZ502 Ram Jet was my first engine of choice, but I scrapped the idea because I wanted decent gas mileage and driveability. Any suggestions?
