Hi Guys, I was wondering if anyone knows about a gm experimental camshaft, I recently picked up a free motor from my uncle because it developed a knock after warming up,he gave the whole motor with a new carter 4bbl carb and aluminum intake included as long as I didn't bother him with questions because it was a rebuild gone sour from a local shop, so I am trying to figure out what this cam may be without ripping the engine all apart I may have to at some point if I can't visually see any problems (my guess maybe a spun bearing) , I looked up the block number and it comes up 1969 camaro 350 and my friend at a machine shop says the heads are 1966 gm the pistons have 0030 stamped on them so I'm guessing 30 over? my uncle said it was a good engine with alot of money in it he's just tired of working on projects,any help is greatly appreciated.
