Doing a 392 Drag Pack NHRA Stocker and there are 2 different pistons listed on the approved list One of the 2 Diamond numbers seems to be a print error. According to Diamond it doesn't exist.
NHRA list:
392 2010 375 1.154 927 1.5,1.5,3.0 0.205 448 600 116 46 1210
JE 307775
Diamond 80041
Diamond 80049
I have no real preference or experience with either one.
Does Anyone have real world experience with either of these pistons?
PM or e-mail me if you don't want to post.
