Will be in contact with Crane in the morning. I will have a pic in the a.m.

Yours were black, remember me questioning you at the shop about the color and we called Crane. Crane told us they were OK and just a different core. Mine are black also. At that time there were not any copper color cores to grind.
Hopefully we will not be doing this three more times.
I would try to find a copper color one.

Mine looked EXACTLY the same. Crane will give you a refund on the cam, but they told me they would all be copper color now, and since my grind even had a new part number, I figured all was good. But then I recieved my NEW cam from summit and it was black!! I will never deal with crane again. Make sure you ask supplier to check color before they ship. A friend/well known local race engine builder also quit using thier roller lifters 6 years ago because of breakage, and is telling me to yank mine out now, and go w/ comp, even though I'm not even buying parts through him!!
Never heard anything bad about Comps stuff, and that what I had always used.....wish I had stuck with it........
Won't forget all this effort that never should have happened. I want to know where my paycheck is for being part of Cranes R&D dept. !!!!

Sorry for your problems also.
Just spoke with Crane and they had no copper color ones on the shelf, but they are going to grind one today and ship it out next day air for me and then I will return my old one to them for a refund. Tech was very nice and helpful, lets wait and see if they stand behind there product?????

Re: Crane Hydraulic Roller cam failures
Don't get me started again you guys. When I broke the second cam in the same motor, Crane tech suggested that something must be wrong with my rotating assembly causing weird harmonics within the motor and transmitting to the cam....... So we took the motor completely apart, had the crank, rods, pistons, balancer, flywheel checked for balance, had the cam bores checked for alignment, on and on. The machinist found absolutely nothing wrong with anything. So I called Crane back and told them this. Only then did I end up talking with the senior tech guy and he admitted that they were seeing this mysterious breakage with the black cams. So now I was out even more money needlessly. Unbelievable!!!! The fact that Crane gave me another new cam is almost an insult.
