What engine is this?

[j.m.]

Bore is 84mm, late style dipstick and air pump bracket, I don't particularly feel like pulling off the oil pan to see what the crank is. Any ideas what this came from? 

[Drosselhebel]

It's a '68-'71 1600 engine. The dipstick tube is not really the later style. If you remove the bracket you'll find a large square hole behind it instead of the hole with press-in sleeve of the later 2l engines. The square hole is a bit further forward on the block iirc.

Thanks! So potentially someone put the air pump bracket in there.  Any idea if these blocks are okay to bore out and use as a 2l? 

[Drosselhebel]

There were a couple of different versions of the air pump bracket, with and without the dipstick tube integrated.

 

Re: boring to 89mm I've seen it done, but I sure wouldn't attempt it. Not enough material in the cylinder walls to make it safe.

Is there a VIN on the flat boss between the 2 bolts that would hold the starter?  You may need a wire brush to read it.

+1

 

And there’s a casting date on the right side of the block, generally in the vicinity of the number 1 and 2 freeze plugs:

Yes, I thought about cleaning the rust off the VIN tag but figured someone would know from the bore and piston done shape.

 

Assuming the rings are frozen, what would the desirability be for this lump? I'm guessing the 121ti head I got in the group with this engine is what was originally on there.

There is very low demand for the 1.6-liter blocks. Just as Drosselhebel noted, there are people who claim the 2.0 and 1.6-liter blocks are virtually the same and, therefore, the 1.6-liter blocks can easily be bored out to 89mm. But other, equally-qualified, people say “too scary!”

 

This block originally had a 118 head. I believe all the 121ti heads were intended for 2.0-liter engines. An un-cracked, un-corroded, within-spec 121ti head is a valuable commodity.

Thanks Steve!  I'm thinking about sending this block to someone who needs a 2l, I'll let him break it down and make the decision if the walls are thick enough to open up.

 

The head (and all the other parts I got from this old feller) is mildly corroded and severely crusty with centuries of grease and crap all over them but I don't remember much damage, I'll clean it up and see if anyone wants it.
