I CNC machine alot of Dart big -M blocks and this is what useally needs to be addressed.

Some block notes:
I deck all of them to a finished number depending on gasket & desired piston height
Block needs to be honed with a plate or bored & honed depending on bore
Bottoms of bores need to be chamfered
Most need the lifter bores honed, at the least checked
Most need line honing
All pipe threads need to be retapped
Oil return from fuel pump cavity needs to be done
Core plug holes need deburing
CHECK THAT THE DISTRIBUTOR GEAR DOES NOT CONTACT THE BLOCK BY THE CAM.
