3.875 Piston Skirt Length ?
« on: Wednesday, December 12, 2012. 11:26:41 PM. »
    I'm thinking about buying an Ultima Fatso shortblock but it comes with the warning that HD piston skirts need to be notched.  It would be nice to find a set of 3.875 pistons with short skirts that don't need to be notched. Any ideas?

You need to know which stroke.Pistons are different between 4" and 4 3/8" stroke for that same bore.        Coff 06

Some of these shorter Tuna cans will try to turn sideways,,, causing that dreaded Piston Slap...
CAN BE, Much more forgiving with the longer skirts.
