This is my first attempt at a port and polish job on the sleeve and crank. This motor is a wore out 3.3 I used for practice so I wouldn't destroy a good running motor. I still need to do a little work on getting the grind marks smoothed out a little more but I think even what I have now would run pretty good.
Let me know what you think.
Crank. I did a little knife edging on the closing side of the port and scalloping on the journal end of the crank.
