I've searched and searched and found very little info on these cams, part number M-6550-M50GTE. They're on clearance for a great price right now, car currently makes 417/397 with headers, offroad h, cai and aed tune. I've seen a few threads showing people getting 15-30whp gains but info is scarce. Not looking for a crazy high hp na build so $1500 for comp stage 3's is a no go, but if I can squeeze out another 15 or so hp for less than $200 plus however long install takes me, it doesn't seem like a terrible deal. Thanks for your time fellas.
