Hey everyone,
I recently picked up a mystery camshaft as part of a package deal. The only marking on it is Norris Cycle D5.” From what I've gathered, Norris may have some connection to Megacycle, but beyond that, I haven't been able to dig up much information. Following megacycles guide I believe the cam lifts would be around .324 and .283. Someone said the rocker ratio means you have to multiply that by 1.2 for the valve lifts, so somewhere around .39 and .34.
Has anyone here come across this cam or know anything about it?
