I am also interested in how to do this to 1750. I have both kinds of spin-on filter adapters, the Wes Hurlock one, and the other one that's billet alum. Both of these take off from the canister port on the block, and locate the filter either out (Hurlock) or fore and down (the other one that the name escapes me). I'd like one that locates it where the 2L motor has it, like this one shows. If you have any info on it, I'd appreciate that!

Is this a eurospec 1750 with Webers or a US version that originally came with Spica, then converted to Webers?
1750 Spica blocks in 1971 had the spin-on oil filter on the front cover.

My 71 spider with 1750 and Spica has canister type filter, not front cover spin on type. Hence my question about this conversion.

Late Alfetta-era 1800s had spin on, as did late 1600s (only after US era). So maybe it's a later 1750 block and cover? They have to go together, you can't mix and match, as the direction of the oil is reversed depending on the filter location.

This is an old thread from Jerry in which he states he has a 1971 with a 2 litre motor. I guess it could be a different 71, or he could have installed a 1750 in this car, or this could explain the visual on the motor and the 2000 badge on the rear valence. https://www.alfabb.com/bb/forums/spi...-not-fire.html

I have a 71 1750 Spider- this is my second 71. Both came with a canister filter, but I replaced the filter unit on each of them with a spin-on filter using a Hurlock adaptor. The adaptor is just a simple one-piece bolt-on with no other modifications necessary. So the filter is not definitive as an identifier.

As for the “2000” badge on the tail, the U.S. 71’s did not come with a “1750” badge but with an ”Iniezione” badge on the tail. There ARE 1750 badges for Euro cars but they’re hard to source here in the states, so I don’t think the badge is definitive either.

The easy way to confirm for everyone that this is a 1750 is to take a photo of the front of the head showing the triangle like this:

As a point of interest, here are the two spin-on adapters I was referring to

As you can see, I DIY’d an apapter for the hurlock one to add the oil pressure idiot light.

When I run out of canister filters one of these is going on the spider. I’m not sure how they will fit/ interfere with dipstick tube or (in the case of the hurlock) the motor mount

PS Charlie — in no way do I mean to hoghjack your thread. Given the car is sold, and a search for ‘oil filter placement 1750” or some such will point to this thread, I thought it appropriate to add my photos. If you want me to I’m happy to delete them and start another thread! Wish I was closer I’d have bought Jerry’s car— such a great guy....😔

Guys.

As far as I know there were no 1750 engines with the spin on filter on the front timing cover. The 1750 blocks have the filter mounting on the block itself.

So that looks like a 2000 Motor, which were produced in 71. Also I'm pretty sure there's a 2000 badge on the back of that car. But the way to know is the check the engine number. 00548 means 1750, and 00512 means 2000.

I think Charlie is going to post up photos of the head with triangle / circle . I have no experience with euro 1750 and I think that’s what this is? The 2000 on back is meaningless to be honest as USA car god no such designation in 71 spider. A mystery for sure!

No Mystery after all this !
My conclusion this engine its the same that's on the shelf of my garage 69 GTV 1750.
Spider engine Izione 1750 converted to Weber Carbs.
It has the Triangle symbol on the front head stamped. Engine #AR00551-05656
My 69 GTV engine #AR 0055102290 Mechanical Injection.
Regarding the Spin on Filter I want to say it was converted upon rebuilding the motor at Alfa experts.....I want to say it was a 2.0L front cover adoption....and oil flow from canister was blocked as you can see on pictures. Don't ask me how it was done but it sure works perfect.
Hope this will explain all the nonsense on this thread.
Pictures attach bellow!!

Mr Jethro ,there is always room to learn something about Alfa Engines! 00551 means 1750 ! or not? you must be a hell of an expert I must say.
