1750GT To follow up and provide closure (NPI) on the TBI screws. The ones I ordered were a perfect fit...

...the ends were indeed slightly hollowed out to allow them to be peened over. I was able to do this by backing up the screw head with a screw bit mounted to an extension piece clamped in the vice. Though out of fear of over peening and possibly splitting the screw head....I was not very aggressive with this and didn't overdo I also applied loctite for good measure as well.

Finally ...the intake system is completed and mounted to the up is the air box.

1750GT With engine side mounted on the stand, finally I was able to install the rear oil seal...

Attachment 1594164

...mount a degree wheel for timing the engine...

Attachment 1594166

...I made an adapter from a spark plug to mount my dial gage....was then able to set TDC accurately.

Attachment 1594168

...with TDC set...I zeroed the degree wheel....then mounted the dial gage to measure the valve lift per procedure outlined in the factory workshop manual. No surprises here....and it went rather quickly....thankfully all to within specs.

Attachment 1594170

Finished off the rear of the engine with installation of the clutch and friction plate..

1750GT I built a modified adapter for my generic engine stand so that it bolts to the side of the block at the engine mount point. With the back of the engine now fully accessible and clear.....I can finally mount a degree wheel to set the camshaft timing, finish installing the oil seal, flywheel and clutch.

Gents..that blade is in fact a new one bought almost a decade ago...I see why you're pointing it out as the color did yellow a bit already. Then might have been that way even back then....since I think it was a NOS one and not a repro. I'd have to search through my invoices to know for certain...suffice it say that there are no cracks or nicks on it at all...and is still flexible so I'm happy with it as is.

Engine wise...I'm still waiting for those throttle body screws to come in which is holding me up from finishing the TBI' I started the refurb of the Marelli distributor.

ossodiseppia Rossano, is that a used fan on the water pump? I encourage you to replace it with a new one. It's cheap insurance.

exhausted Rossano it is looking like straight out of Arese, but please shout your self a new fan blade, the old yellow one is done and while your at it get the radiator overflow bottle too.

I removed that water pump fan spacer that came with the car after some of you pointed out that it was required only with the aircon installation and sure enough, after I checked some photos of the engine during the teardown phase....I noted that the crankshaft had a double pulley (also the aircon version). I installed the correct single style pulley from a spare engine.

ossodiseppia WOW!

1750GT One more detail out the way is the oil filter assembly. With Osso's very nice water slide decal and clear coat's a shame the filter will be hidden low in the engine bay.

Thanks for that tip. I found these with a torx head and although not 100% correct they have hollowed tails which allows them to be peened or expanded for safety.

Attachment 1588182

and these as well from the same seller (can't tell if the tails are hollowed though)..

Attachment 1588184

I ordered a set of both styles from this seller.

ossodiseppia Rossano, reach out to @Gordon Raymond. Being a carburetor guy, he might have some suggestions.

The OE ones are also very easy to break off the edges since those not being very deep ...there is less material engaged with the tip of the screw driver....happened to me on a couple of the screws. To remove the screws I had to drill out the end of the screw that was flared out making them all shorter than what I'd like to see. With new screws I was going to flare out the ends....I know some folks are going with Loctite I might have to do the same...unless by some luck I can find the correct ones.

braino yeah. I wasn't going to say anything. I'm sure you're sick of hearing compliments from us plebes

GTA ALFA As always, great work Rossano. That intake looks like a piece of art!
