    Today I finished disassembly, and did some more cleaning. Cylinder walls still look good on the block, cross marks are still there.

              That's the plan. I will run it NA for a while before I go turbo

                    Didn't work on it this weekend. Today I finally fished disassembly..will start looking around for a good machine shop in the northern VA area, any suggestions? that will do the boring on the block to 86.4mm to fit the S52b32 pistons.. CR target is 11.5:1 decking the pistons will be necessary. Oh and the VW lifters came in.

                      Small update: dropped off head at the machine shop yesterday, to get cleaned and get pressure tested, etc. Found a set of S52 pistons. They should be in by monday, and can finally take the block to get cleaned, bored and honed. While I wait, I'm starting to clean, paint, and clear parts to make the engine look clean.

                          You are making me jealous ;)
                          This is what I would like to do to my M42.
                          Glad to see another M42 build. sub'd
                          Wise choice with the late M42 timing cover.

                            Thanks. S52b32 pistons should be waiting for me when I get home from work today, and the M47 crank should be in by Friday, hopefully.

                              If you don't mind sharing, what's an M47 crank going for now?

                                From dealer about $1100 for a refurbished one with bearings.. used ones start right around $500 and up.. the Problem is finding a used crank.. they're not easily available
