And from exp have found that I can seat a ring in a bore in about 2 minutes by hand and they will have a less than 1.5 - 2% leakdown prior to running. If the bore is sized correctly and not worn.

I've got a short block from Kibort with 50k, a set of euro 4.7 pistons from Devek also with about 50k, and a set of new rings from 928Intl. The bores are great and the pistons aren't scuffed at all so I expect/assume/hope it's going to seal just fine. We'll see.

Mike,
all is well as long as the pistons and block tol codes match, otherwise, you will be a bit loose or worse, too tight
Install the rings carefully!

Marc,
It's all TG 1. The _only_ thing preventing assembly at this stage are those darned hollow dowels that locate the block halves. I have one, can't find the other, no luck sourcing 2 new ones from anyone. I'm about to have some made so I can stuff this engine in the weinrot. I'll let you know how it goes.

Thanks again Erik,
It has been downloaded, printed, punched and installed in my 3 ring binder and is awaiting a read. Perhaps this weekend. My latest priority involves whether to cut the crank mains or not. I need to get to the shop to take a look at it post polishing. It's tricky to find oversize (or undersize depending on who you talk to) bearings. The dealer has them for $330! Do you know if Glyco made the original bearings? I found a set of std for $99. Good deal, but I want original manuf. bearings. The weather is starting to warm up here and I'd rather drive the 87 than the 85, I really have to get going on this car!! Thanks Erik, your a good guy.
