Having a limited amount of "spare" caps to work with lessens the chances of a "perfect" fit. They may be close however.

I would add this tip here, if possible try to avoid milling the pan-rails, this is a "down & dirty" option to "shrink" the holes. We recommend milling the caps, more work involved but usually a better outcome. This can be accomplished on a Bridgeport in conjunction with decent rotary table.

After having the procedure finished I would record the center-to-center distance just as a precaution. It's nice info have on the build.

(Add) Hi Ron, Happy Birthday (belated), just saw that post. Stay healthy up there!

Thanks, Gary in N.Y.

P.S. Try to find a shop that can "align-bore", using this method you can actually "hold/maintain" the center-to-center from the mains to the cam tunnel. This cannot be done with "align-honing" equipment! This subject was up here recently about "fixing" connecting rod lengths!
