What engine is this (short block)?

[Zendalar]

I got this extra short block recently with my newest addition -71 1.7L 914 and I was wondering is this an 1.7 too...I am kinda newbie when talking about these TYPE-X engines...

Heres the type number:

S1 12
004.101.101A

Serial:AP 086122

How big cylinders and such can one fit in this, and is it worth it??

Thanks

1.8 series:
AP - '74-'75 VW Transporter - 7.3:1 - 68hp - Only sold in Europe. Came with dual carbs.

You can fit any size pistons and cylinders in any Type IV (late Bus, VW 411/412, 914-4, 912E) case with pretty much the same amount of difficulty. With a 1.8, you can fit 96mm cylinders into the "registers" in the cylinder head without machining. This is 3mm over the standard 1.8's bore of 93mm, and will give you 1910cc displacement.

If you replace the cam and up the compression to a decent level--and re-work the heads to support the flow required--you can have a nice fun engine that makes about 100 HP pretty easily.
