i just installed my bc3+ cams today, and i noticed that the keyway for the woodruff key is a bit large, as in i can move it around. as a result theres some play in my adjustable cam gear , probably 2 degrees. anybody have the same experience? i also noticed that the exhaust cam has huge lobes, bigger than the intake. what's the rationale behind this?

 

the BC3+ cams are not conventional with regard to the design. The intake and exhaust look like two totally different cams, with 1 wild one and 1 mild one. The combo works great in my B17 though.

As for the keyway, mine was nice and tight. Had to tap it in with rubber mallet

 

I had the same problem with my skunk2 stage 2 cams. It ended up chewing up the woodruff key and knocking the cam timing off enough to bend my valves. Hopefully this is not common with the BCIII+ cams. I plan on buying a set soon.

 

well the cam gear doesn't move anymore when i have the camshaft bolt torqued town nice and tight. it's just that with such a large amount of play, you can't really be sure if your cam gear markings are accurate anymore

 

when you installed the cams if you see something that is not right you should maybe try replacing them.
