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...
Yeah, after looking around and seeing how much people want for factory housings, I'm just gonna save up the extra 100-150 bucks and go with a Lakewood scatterproof housing.
