Not sure exactly what yet (other than the visible missing piece of valve). More investigation soon.
I'm more in the process of reverse engineering what I have to build back in to.
The only thing I have firm is what I can read from the casting #s
Z22 block and U67 head.
Bore looks to be standard 87 mm but either through wear or a terrible bore they taper at the top by up to 0.008". This may have to do with the funny pistons (that look like they should be from something with 4 valves because of the cutouts?)
Head is shorter than it used to be because of the last head job I took it in for and it was shorter to begin with.
Cam has an asymmetrical and what looks to be quite aggressive grind.
Were pistons with those cutouts nissan parts or did they come from something else in a quest for a tiny bit less compression?
The only thing I have an attachment to are the carbs and they pretty intake and exhaust manifold. Anything else can be scrapped/swapped. Is Z22 and U67 still the way to go?
The damage to the cylinder walls seems like it could probably be remedied by a 1 mm overbore. Are there 88 mm pistons around (new or from somebody's collection)?

Last month, the throttle return spring decided to jump off its hanger as I was driving down the highway.
Called my father who came and we drove to Lordco for a replacement; sorted in less than 30 mins.
Fun picture time:
I got kicked out of the shop because this will not be a quick weekend project.
I couldn't get a car trailer quick enough and being a cheapass, I didn't get a pro to tow it.
So we put the 4 post lift, I got a truck from work, lined it up, rolled it on, then rolled it off at a level loading dock.
