Sorry, my bad. Just went back and took a good look at the block. Forget the '18 reference, thought you were putting one in to get mobile for some reason (CRS moment). I will say this however. Having been involved with one clutch explosion, I will never have a car that is expected to see more than 5000 RPM on even a semi regular basis that does not have an SFI approved flywheel, clutch, and bellhousing...
