Update:

Things are coming along nicely, albeit slowly. There is something about a 356 project that is like a black hole, time-wise...100s of small delays that make work stop until a missing 0-ring is ordered, etc...

An example would be completely dry-assembling the engine to measure all combustion chamber-related clearances, from deck-height to piston-to-valve and piston/head clearance, etc., etc... Some of this is done w/ modeling clay on tops of pistons, assemble/turn motor by hand/disassemble/measure/re-assemble. We changed pistons and cam, the heads have been cut in the past to an unknown degree. There is a dearth of printed information on the exact stock measurements of a 912 head, (which it has), so measure away I went.

The last guy to assemble the engine was an absolute jackass, it's a testament to the heartiness of the Porsche that it ran as well as it did. He had extra spacers under the cylinders to compensate for shaved heads that were not necessary according to my measurements. At least not with the 356SC cam that I installed, who knows with the goofy off-brand cam that was in it.

Spacers are essential if needed but CR-robbing if not. This whole chapter is a LONG story and my time has been short to deal with it, so it dragged-on for a while. It's now sorted-out and the engine should be completed Monday. I still need to finish setting-up the axles on the the (newly rebuilt) transaxle and install it, then the engine goes back in and away it goes.

I have dozens of photos of the job and tried just now to set-up a Picassa album to post them all on and put a link here. For some reason, Picassa does not want to download onto my computer right now, I'll try again later.

Here are a few randoms, sorry but I do not have time to caption them all.
