Slant Six Crankshaft Flywheel Bolt Pattern Orientation
I'm about to machine a custom aluminum flywheel for my CD009 transmission swap and I am including a 36-1 trigger wheel pattern on the back side. I'm trying to figure out if the bolt pattern on the crank nose is oriented to a specific TDC event so I can place the trigger in an orientation that I will know what numbers to punch into Megasquirt. It seems as though the keyway in the harmonic balancer side is pointing to cylinder 1 BDC, which also lines up with the bolt hole opposite of the offset hole. I've attached a picture of the bolt pattern that I will be machining.
Could some of you guys with a loose crankshaft laying around confirm that it matches on your crank as well?
Thanks,
Casey
