I am needing a set of pistons for a GB2000 motor that has a 4.145” bore. We recently had some work done to our block and had to increase the bore size.

The current part number for our pistons is J&E 281795. This number is listed as being for a GB2000 and an All-Pro 13 degree head and fits a 4.135” bore with 3.800” stroke with 6.00” rods and 1.100” dome height. We need the exact same piston just for the larger bore. We are open to looking at other brands of pistons with the same specifications.

Let me know if you have anything that might work.

Call me again. I was measuring some pistons for you and you hung up or we lost connection. I tried to call back but it was the Terre Haute federal prison. (must be home landline)😀. I do have what your looking for.
