    +.175 stroker crank and UT2 piston in 196 clone.

    Just curious can a person use the UT2 piston with a +.175 stroker crank and a +.010 length rod being that the stock piston is +.020 in the hole in a 196 clone. If I did my math right that would put the piston just below the deck at .0025" has any one tried this?

    looking for someone that can turn the top of a piston down

    I have a pop up piston and if I use the longer rod it will stick out of the hole probably .020-.030 so I will need to top outer edge turned down so I can get it to zero deck height,, a little may need to be milled off the pop up area also.. If this is something you think you can do let me know..
