Spun dampener

Thanks, Been looking all over the web for info and the only real thing I can find is the cam has 2 gear drive to make the cam run opposite the crank. It came with a normal oem chain and gear set installed which looked original with oem penstar. The oil pump camshaft gear meshed fine with a new lunati cam, but it did have that thrust bearing under the distributor. That is what is throwing me off. I cannot find anything that makes me believe it is a reverse rotation engine. The dampener is also a head scratcher. The starter goes in from the front of the block on drivers side like normal. I really just do not know.
