Alfetta 1600 engine block, or is it?

Hi all, usually over on the GT forum, but hoping you can help me out.
I've an engine block which I believe is a 1600, with the number AR 01600*020624+
I've been reliably informed that it Could be off an Alfetta?
Can anyone confirm this?
Thank you.

Alfettas have transaxles. So where you normally would put a clutch on the engine block, you connect a driveshaft with 3 bolts. That's all I can come up with. I can't tell you more about engine displacement.

Engine type AR01600 is a 1600cc engine originally fitted to some Alfettas and Giuliettas starting in 1983.

The rear of the block is the same regardless.

I've owned a couple of these. Of course I will defer to Jim in relation to actual engine numbers but some background may be of interest.

Alfa started putting 1.6 engines into Alfetta's in 1975 and continued right through till the end of 75 production. They also appeared, as Jim says, in 116 series Giulietta's from '77 to '85. They were built in large volumes, around 100,000 for the 75 alone.

They also continued to build 1.6 Spiders for European markets all the way through to the end of Spider production in the early 90's. Most if not all of these were carb's as well so for all intents and purposes their blocks would be interchangeable with contemporary Alfetta / Giulietta / 75.

The external dead give away is the combination of late model features, like the front cover mounted oil filter and 6-bolt crankshaft, with the lower block height of earlier 1600's. As in, the head is flush with the top of the water pump. Of course they also have the 78mm bore and if you're familiar with later engines the casting marks around the block will look the same.
