Re: Fuel efficiency...what MPG do you get?
On the '86 crewcab, I don't wanna know! It's an off the road only truck at the moment.
'84 Chevy flatbed dually with around 60,000 original miles
454/SM465/4.10 D70 cab-chassis rear
I figure about what, 6? in town and MAYBE 10-11 highway? I hadn't driven it on the highway long enough to check. About a month ago I installed a high performance cap/rotor, then a set of Bosch 8MM wires and R45TS Delco plugs gapped at .045. Monday the timing(4 degrees before TDC) and carb were adjusted and she's running good!
