066 Meteor piston is .020 higher then 2083 OEM piston. Squish with gasket, OEM piston was .041. With 066 piston squish is at .021. Comp is at 170 pounds. The 2083 rod is wider than the 066, piston needs to be opened up. Runs good .

Ron I paid closer attention to my measurements this time and measured the squish closer to where the piston and cylinder  intersect.   I came up with .0245 at tightest on the afm 066 piston with used gasket.

The oem 505 one on the other saw when I installed today was .040 with new oem gasket.  I checked the 425 top before puling it and it was .0435 with used gasket.
