I finally have all of my belts reinstalled on my 308qv. The motor is out of the car on a crate. Would you bother with a degree wheel? I have all of the marks aligned, ie. the PM14 mark is dead on and all the cams are dead on. I ask this because as I come up to pm14 on the flywheel the intake appears to open at 16 BTDC which is correct, but the PM58 looks more like 10btdc. But, this is just a fast visual not accurate with a dial indicator ( I dont have one) what would any of you do? Would ferrari techs say that this would be ok as long as the marks all line up? Opinions greatly appreciated.
