What mileage does your slant six powered ride get?
Just checked the mileage on my 84 D100, on fillup, yesterday. 15.x mpg. that was just normal driving around, some hywy, some local, no interstate. The only other checks I have made was when towing my race car, which got 12-13 mpg mostly interstate.
Slant six, all emisions removed, super six, A833od, 3.91SG 8 3/4, 225/75-15 tires, 30 gal tank, A/C, aftermarket cruise control. Just got the truck this summer, and have no idea, what, if anything is done inside the engine.
I have a 64 Valiant 4dr, that was built for mileage. 170 slant six, 3sp stick, Don't remember the rear gear (2.93 I think). I does get 27-28 on the interstate. Engine was built for mileage.
Bored and honed .060 with a block plate, decked, balanced, Stock valves, but pocket ported, head cut for a true 9.5 CR. Mildest MP cam, and 340 springs. Windage tray, crank scraper, Stock intake and exhaust manifolds, larger exhaust pipe(s). Ign was points, but just converted to EI/HEI, which hurt. Dist curve is all wrong (need to recurve). Future plans (after some body work, rust repair) are A833od conversion, Holley economiser 1 bbl carb (and/or try some other carbs).
