What if I push the date to the right for late NOV, early DEC? Any impact on more paticipation from you guys doing builds? As for my motor, it lost compression in # 6 cylinder, 145 to about 90 during the last Dyno. I was very fortunate because it only cracked the piston between the rings and didn't fragment while in the motor. To look down into the motor you wouldn't have known. I thought I noticed a hairline crack once the piston was out and when I tapped it, a section came out. Decided at that point I would do a complete SPZ short block topped off with IPP heads.
