Typical that just after I pick up the block i come down sick and am out of action for a week or so. Crawled out of bed today and was feeling a touch better, so started pottering around building the engine.
First up was doing all the calcs for the piston/rod/pin combos:

Then file fit all the rings, which mercifully didnt need much more than a touch on the linisher.
Add one set of ACL race bearings:

Add rings and spin them all around to different parts of the piston, and compress:

Check bearing clearances with Plastigage… then find out that your plastigage has gone hard, and go buy ACL Flexigauge. Check bearing clearances with Flexigauge:

Rinse and repeat 4 times while fielding calls from OS and small children, and you get this:

Subsequently realise that you cant remember aligning the rings on piston 2, and so remove that to check… thankfully i had actually done it.
CSH time: When i was in high school a kid a couple of grades above got a Datto 1200 for his birthday and proceeded to do it up, so that he could drive it to the Year 12 formal. When it came down to the wire he started it up and it was spewing smoke out the exhaust. Nevertheless he drove it to school proudly.
What went wrong? Well he was a little bit OCD with the car, and so lined up all of the piston ring gaps on the pistons…. :knock:
Taught me that you shouldnt line up piston ring gaps, even before i had built an engine.
Anyway, now waiting for replacement valve springs to come for the head, and then I should be able to screw that together and start thinking about closing up the engine.
