Lee, this will probably make some people scream, but I worked in a machine shop in the 60's where we did this on performance built inlines all the time. If the block was to be finish milled .060, then we milled it to about .055. Then assembled the rods and crank. Then put it back on the mill(block assem. up side down) with two pistons sticking out and made the final cut. Then rotated the crank with two more sticking out and made another pass with the same setting until all 6 or 8 pistons were done. I know this gave zero deck height but they screamed and I never saw one come back with a piston problem.A lot of these were motors that were driven daily and raced on the weekends also. Paul
You may be disappointed if you fail --- but doomed if you don't try!!
