Cost-effective, high-mpg combo for SBC in 1500?
Starting point:
1996 half-ton pickup extended-cab fleetside 4wd auto & air
It's decent on gas so far, but I want 25+ mpg highway (28+ would be even better). I want to preserve sort of a medium off-road capability (nothing overly extreme, but not completely wimpy, either).
----------------
Eventually (maybe 40-50k miles from now), I will want to lift it & put larger tires on for mainly cosmetic reasons; if I could keep 20+ mpg with tires in the 33"-37" range (haven't yet decided), I'd probably be quite happy.
----------------
Any ideas for such a combo? I figure aluminum heads are just about mandatory, as is higher compression for thermal efficiency -- but there are different combustion chamber shapes and all sorts of other things to consider.
Anybody with real experience in this area, feel free to share your combo unless its a secret: this is going to be a slow build, with incremental gains, but I need to plan the whole thing before I get started. I don't want to open the engine, do a mod, button everything back up and then have to get another set of gaskets 6 months down the road.
Thanks for all the helpful info!
In our neighborhood, 2 blocks down the hill was a gas station that (to me) all the cool car guys hung out there. 32 coupes, 33 & 34 Fords as well, a sweet 56 Ford Beach wagon that was setup gasser...
