George

VERY interested in this--and have a couple questions.
You moved the main bearing stud centers out to an area where the rib in the block is thin--what did you do about this? Also what do you intend to do about the misalignment of the lifter holes with the respective cam lobe?
Also, I wonder why you bored the big end of the rods on your lathe? I always did it in the mill, to insure parallelism of the hole, with the just bored wrist pin hole--neglecting inevitable table rock.
Wondering also if you did the line boring your self? I have line bored the mains on both Ford and Chevy fours on the Bridgeport with a truly Mickey Mouse rig--but the reground crank spins in the inset bearings--so I was happy. The table is longer than your Moog, admit ably. Looked for a photo of this, but I guess that it was on film, and now is lost in a one of many boxes.
