Piston ring end gap for 340

[stoney79]

Building a 340 trying to set ring gap but lost insturctions. The rings are made by sealed power and the pistons are Keith Black. The bore is 4.070. Any help would be greatly appreciated.

If they are the KB243 I have them in my 340. The top ring for .030 over was .026. The second was .012 to .014.

Do it by KB's spec for the ring set up or you could be very sorry. Go to the KB site and look up the install instructions

KB hyper pistons require larger top ring gap due to the ring being higher on the piston...

follow the instructions on their website or the instruction that came with pistons..
