Hello there! i'm seeking some help for my F360 I had a problem with the oil pump which one of my mechanic friends has repaired and he has fitted a new cambelt kit and lower front crankcase (the section with the 2 lower pullies for the 2 banks), now the car runs, but you can hear a backfiring through the inlet in the plenum chamber, we "think" the cam timing is out, is there a workshop manual available anywhere? the car is very rough at idle and you can smell it overfueling this car had problems in the past with the throttle body connections and the MAF sensors too (one of the manifolds started glowing red at idle!) it gets a hard life (track car) but has been problem free until now! any help appreciated!
