This is a newly machined, super light weight, aluminium adjustable cam pulley for any model year Fiat or Bertone X1/9, or any other Fiat with SOHC 1100 / 1300 / 1500 engines.
This gear accommodates a stock belt, and includes the belt guard lip on the backside of the unit, as required on 1100 and 1300 engines, but can be used on 1500cc engines without issue as well.
If you've had the head or block shaved during a rebuild, you need an adjustable cam pulley to get your valve timing right! Billet aluminum insert with lightening holes, six mounting screws to assure against slippage.
This is an excellent unit! You can find up to a 10% increase in HP and torque by having the valve timing properly set. Weighs only 16 ounces!
New and unused.
