That's not enough. A good tune is the first thing. Check the timing & vacuum advance. If you have a Roch. model B carb it is easy to take off the top & check the float level & make sure the power valve is free. If you pull the carb there is a hole in the bottom. It has to have a gasket that allows vacuum to get to that hole. You don't need any high dollar plugs. That should get you 12-14 mpg. I f you do a lot of highway driveing you will want to go to a better gear ratio like different rear end gears or an o-drive trans. Swapping to a v-8 & auto is not too difficult on this truck but it all depends on your expertise.
They say money can't buy happiness. It can buy old Chevy trucks though. Same thing. 1972 Chevy c10 Cheyenne SuperIn the Gallery Forum | | | | | Joined: Jan 2010 Posts: 41 New Guy | | New Guy Joined: Jan 2010 Posts: 41 | thanks wrench. i'll check that valve and send her for a tune. | | |
