I just bought a 88 F150 351w 3.08 rear. I am only getting 12MPG and would like to advance the timing to see if I can improve mileage. Question is how do I advance the timing to 14 degrees?
Also the truck has a stock exhaust system. Can anything be done with the exhaust to increase mileage? There are no emmissions were I live.
Any help would certainly be appreciated.
Thanks
Bill
