My 422 smallblock build

I didn't see where you notched the bottom of the bores to clear for the rods?...
Not needed with this combo. The rods are 6.125” h-beams from Callies with arp 2000 12point bolts. Lots of clearance. I’ll take pictures and measure the exact clearance when I get to that point. I did previously have all piston/rod assemblies installed for mock up with no issues.
