LS1 Crank to Flywheel bolt pattern?
LS1 Crank to Flywheel bolt pattern? Quick question for you guys. I'm putting an LS1 into my boat, I ordered an LS1 PTO adapter from CP Performance, but it doesn't fit. Their adapter is 3" center to center on the bolts, and 2 of my LS1 cranks plus my flexplate have 3.15" center to center measurements.
Do I have a couple of oddball LS1s, or what? CPP said they sold a couple others and no one else but me has fitment issues; and that the company that built the adapter has been using them on their LS1s...what am I missing???
