Wondered what the ring gaps should be, top and bottom, on a wiseco 426cc 11/1 88mm piston? I made this thread a long time ago and can't remember what its supposed to be and can't find the thread. Thanks

i had that piston....can't find stats....but found JE 88mm 11:1 so should be close.

.20 -.35 top ring service limit of .50

.30 - .50 2nd ring SL of .65

.20 - .70 oil ring SL of .90
