    Beta cam identification

    Hi my name is Michael and I'm a new Lancisti from Denmark, I actually dont own a Lancia but a Fiat 124 Spider with a 2,0 Beta engine No. 828B1000U324169, these cams were installed, but I couldn't use them due to the missing drive for the Fiat dizzy.
    There is nothing written on the cams except for 10,3 R, I've attached some photos of the cams, and I hope to get wiser about this before putting them up for sale.

    No idea if they're aftermarket cams but probably not; they appear to be for a Beta with fuel injection, going by the distributor drive slot on the end of the exhaust cam.

    Hi Tye

    That's very interesting, was it only the fuel injected Betas that came with he slot in the end for the dizzy drive?
    They came out of my new engine it ran with dual Dellorto 45 mm DRLA carburetors, I think these cams are pretty hot given the lift (10,3 mm) and the duration that's maybe 300 degrees.

    Regards
    Michael

    Judging from the lobe profile, those definitely look like some pretty hot cams. They remind me of a pair of 42/82 Alquati cams I once had. Stock cams would have a rough casting look between the lobes and no multiple holes on the sprocket end.

    With hot carbs, hot cams would make sense to take better advantage of the better breathing. AFAIK, only FI Betas came with cam-end driven dizzys as stock; however, that dizzy mount may have been a build choice, so the engine might not have been FI originally, just a matter of using the FI-style cambox. Speaking of, you'll want to use Fiat camboxes for your Fiat, as the Lancia camboxes have altered oil drainage to account for the canted-over engine in the Beta. If a cam-end dizzy won't fit in your Fiat, you might consider using distributorless electronic igniton to keep the hot cams you have?
