My '75 Scamp 383 Build

LOL! Yeah, slow and steady over here... Starrett inside Mic on the way via UPS. I have to get a better measurement of the bores. Too many measurements already that are right at the edge of tolerance OR .0005 beyond. Low buck build, trying to avoid machine shop.

IMO, you can run outside spec on the bore a bit, as long as the ring gaps are right. In other words, you may use file fit. Not the optimum, and may not last as long as a new bore, but will save money and last a reasonable amount of time. The crankshaft is where I will absolutely NOT cut corners, no ands, ifs or buts. That's just me.
