Do all the basic stuff for starters, compression, timing, then where is map voltage at under load. Also at 100 KM per hour and top gear where is the rpm at? 3 speed auto or overdrive auto? does the torque converter clutch engage?
318 is a good and realiable engine had one with over 200.00 miles in a Dodge 1/2 ton van with a camper top that got consistently 16 miles per gallon when highway driving. You should be able to get near that
