M64/70? ...993 cup case
 

Hey Guys -- What's your thoughts on the below? Looks like someone got a little careless at the factory on numbering case. I believe 2nd number from far right is 7 (over stamped on a zero).

Are the cylinder spigots machined for O rings, if not it’s not a cup case.

...yep, has cyl O-rings and the o-ring groove at case parting line for through bolts.

about a dozen years ago i purchased a U-haul full of a partial car and parts from a stuart of synergy racing. Had lots of factory race bits -- 993 rsr heads, 964 rsr rods, 993 rsr p/c, this case, rsr headers, etc.

Did some checking back then and was think'n 993 or 964 rsr case, and did not even think to see what cup case numbers were.
