Engine is a 74 Z1 I have a welded crank from a z1 to start the bottom. 900 head with 1075 10,51 compression. 390 lift cams. ported head under buckets on exhaust' stock valves. Any thoughts?

Sounds like what i want to build-see abused z1-900 post. Can you tell if the block has been clearanced-machined for the cylinder to fit in the block. Is the cylinder original?

You mean 900 block bored to 1075.
1045 is max on std liners but leaves the walls too thin for my liking.
It must have had 1015 liners fitted to get the 1075 capacity.

Pretty standard issue stuff for a nice boost over stock. Should make a nice ride that's very easy to tune, smooth and reliable....
