On Sale For:
This is a set of performance intake and exhaust camshafts with nitrided lobes for Fiat DOHC engines. These cams have a higher duration and lift than a typical stock camshaft and are great for mild street performance and a good solution for Fuel Injected cars.
These are a matched pair, with a gear on one for driving the exhaust cam mounted distributor on Fiat 124, 131 and Lancia Beta cars.
Note: Although the exhaust camshaft has a drive gear, it is fully compatible for installation in DOHC motors that use a block-mounted distributor, such as 1967-70 1438cc and Lancia Beta 1979.
These cams are regrinds from a leading camshaft supplier that we exclusively use in all of our race cars!
NO CORE Return REQUIRED.
Since these cams are regrinds, they have a smaller-than-stock base circles so you will need to take up the difference in gap using some combination of larger shims, more deeply cut valve sets, or lightly milled cam boxes. An adjustable cam gear is also recommended to dial in the cam timing correctly.
Take a look at the multiple pix, for detailed cam doctor analysis.
