328 ignition coil specs

I was hopeful someone might be able to tell me what the primary/secondary coil resistance specs are for a Magneti Marelli AEI 500C ignition coil. Searched here and found a lot of interesting information regarding coils and aftermarket ignition options but no specific specs on the original Marelli coils fitted on the 328. I also checked the owner's manual, 328 tech spec document, and the 308/328 WSM without any luck. Thanks in advance to anyone who may be able to guide me here.
