so I'm getting ready to reseal my engine and there is a noise ill be investigating as well but while I'm in there i was thinking i want to upgrade the cam shaft too. I'm not sure if the make a stage 2 camshaft for the b2600 2.6L engine. i have found a couple on line. but I'm not sure if the 101 stands for stock and the 450 stands for the amount of lift this cam will offer. thought id put it out here see if anyone has done thins before and maybe i can get some ideas.

here is the link to the 101 cam shaft
