    And don't forget guys, the valve timing was probably out from the factory spec when it was first built..

    You need the dial gauges to do the job properly, you can't rely on paint marks when replacing the belt!

    Also please note that the flanges of the bearing-rings have the right position, they "guide" the timing belt. And carefully check the play of the bushing/bearings
    around which the tensioner-arm pivots.

    Halfway through reading this I felt quite confident to crack on with this job. After reading to the end, I am more cautious. I would happily swap the belt using the magician's assistant method. Less happy about the static timing setup as the timing would need to be cock on.
    Is it really true that cars left the factory de-tuned deliberately by altered timing?

    BTW can the cambelt be clamped in place with vice grips / cable ties / wedges to allow the tensor too be removed? Used this method on 911 engine, to replace failing (oil fed) tensioners which leaving duplex cam chains in place. My mechanic thinks I am a lunatic, but it seemed entirely logical to me.

    Well there are plenty of stories of timings be well out, but if you wanted to reduce the power of a production engine why in the name of god would you do it like that?

    Because its easily done on assembly.. don't forget at the time this was all very low volume stuff assembled be hand

    We all know the story about the 360 Modena being less powerful than the average 3200GT on low boost

    Luckily for Ferrari the old Maserati 3200 bi turbo motor wouldn't pass the Euro 4 emission's, hence the Mk2 4200 with the Fiat/Ferrari engined derivative

    But is going to be noticed the first time someone does a timing belt change. OK so that's a fair old while but surely you'd change the technical data *as well*
