A 0.060" undersize regrind will get you +0.030" at TDC and +0.030" at BDC. So a 318's 3.31" becomes a 3.37 stroke. This brings a 318 out to 323.76 CI. Add in an over bore to clean up. At what costs? Just to get closer to a 0.0" deck? A 0.030" more crown will not give much toward 0.0 Deck, better but still a long way off.
Now do this and add in a longer rod to get to 0.0 deck or even better.....
No, that’s not how it works. A regrind will net u nothing for stroke. U have to offset grind it. Re read my explanation. When u offset grind it your taking the minimum off of the outside and taking the max off of the inside of the journal. Kim
