Re: Are you really concerned with gas milage on your truck??
not really, but i do think a little tuning with mpg in mind make for a better-running engine. lean out the idle and cruise, make sure the vacuum and mechanical timing curves are dialed in, that sort of thing. but a little better mpg is more of a fringe benefit than the main reason to do all that.
my 72 has three tanks so i get tired of driving a long time before she runs out of gas!
