Assuming you're reletively sweet to the gas pedal, you may want to check your timing, tune up, carb adjustment, etc. What carb is on the truck? You don't need much more than a 500 cfm carb on a 350.

Post by: travisr1988 on June 22, 2012, 02:45:01 pm: My right foot is gentle on this truck, tge carb is a rebuilt quad my dad
rebuilt, has been adjusted. We suspect a bad timing chain so we're replacing that on saturday, it does burn oil and the ••oil pressure drops sometimes at idle and it seems to drink more gas when that happens, it has worn out 235/85r16s on it and a 160°tstat

Did you get the chain replaced and did it help?

Post by: travisr1988 on July 11, 2012, 11:57:23 pm: Replaced the chain, found the distributor advance wieghts were siezed and the distributor was burnt up, my dad says the truck shouldn't have been able to run at all. But we fixed it and it's now getting 12-13mpg. next is tires and then we can try getting that F.I. Setup on it.
