    It's a carbed 1500 engine, I think out of a '79 X. It looks like it has provisions to mount a fuel pump to the back of the cam carrier. The cam has a corresponding lobe between the #4 intake and exhaust cam lobes. While I never saw anything mounted there, it looks like something had rubbed on the eccentric lobe at some time. One clue? There was a decal on the valve cove that read: Spider 1500.
    I have another cam carrier that has the same "fuel pump" mounting provision, but the cam does not have a lobe between the #4 valve lobes. The cam does have a slot on the end that would mount a cam driven dist. such as a Strada would have.
    Can anyone tell me what these engines were in?

    Egr or some other emissions crap

    That could be a block off plate for a mechanical fuel pump

    I don't think it's the EGR - that monstrosity is mounted on the block below. And talk about ALL the emissions crap! What a PITA. I'm sooo glad Fiat went to FI.

    I have a ‘79 X and it does not have that opening in the cam box.

    Not emissions control on a North American 79 X 1/9. I have never seen that on any X. Keep searching.

    Jefco It goes WHICH way?

    Volvo B20 engines with Bosch K-jet ran a vacuum pump on the fuel pump mount on the block, to ensure power for the brake servo regardless of manifold vacuum. Were there any 1500-engined cars with a vacuum booster that this might have been done for?
  8. Looks like a Fiat Strada 1500. Here's a photo of a 1979 Strada engine bay, and you can see a fuel pump mounted just to the right of the air cleaner.

    one way to tell if it came out of an X1/9 would be the thermostat - I think Paul is right, this is a Strada engine, but I didn't realize that they had the same cam box bosses for the dogbone engine mount.

    Sure looks like the mechanical fuel pump block off plate I just ordered from VAS:

    I think Paul must be correct. Someone must have mounted a Strata engine in an X. I thought Stratas had cam driven dist. but I thought the differences in the cam were limited to the slot on the end to drive the dist. When gathering cams for Midwest Bayless I did dig out a cam with that slot, but no fuel pump lobe. The '79 pictured above does not have the cam driven dist. That shows how little I know about Stratas.

    Did any Stratas ever come with an automatic trans?

    BTW - That engine did have all of the same emissions "stuff" an X had on it too. It's a wonder they ever got them to run at all with all that crap.
    BBTW - The valve cover that had the Spider 1500 decal on it was not a Strata valve cover. Has anyone ever seen such a decal?

    Actually that is the ultra, ultra rare Abarth head with mechanical fuel injection; that is the drive for the injection pump. They only made about 4 or 5 of these heads. Worth a lot of money!
    O/k/, not really. But wouldn't that be nice.

    Yes, but it had the correct spelling of SPYDER on it....

    Yes, Paul is correct, this is a Strada cam box. I have one of these attached to a cylinder head that I pulled from a wrecked Strada 1500 engine a long time ago.

    Yes, the Strada was available with a VW-sourced 3 speed automatic.

    Really? I think it's time for a new thread.

    Yes Steve, that's it. And you are correct, I spelled it like a 124 Spider :(
    Here's a (bad) pic of the one I have. It's very difficult to see (and it's upside down).
    P1040359.JPG I also included a pic of the head it's mounted on (may not be the original head - I don't know).
    It looks like a 12mm 10 bolt carb head. Does the casting indicate it was cast in 1978?
    The question is: Why would it have a Spyder 1500 decal on it? Was there a Fiat called the Spyder?

    X1/9 is a 128 Spyder... hence the chassis designation 128AS

    head looks like a november 1978 casting production, so that's a real early 1500 head.
