I have a replacement cam for 460 cyclone engine. I think it was a wolverine that came from a mercruiser dealer several years ago. I never used it in my 427, needless to say I lost the cam card. Does anyone know the specks for this cam or the original cam?

I would use caution in determining whether or not this was actually a genuine 460 Cyclone replacement cam. The original cam was ground by UltraDyne for Mercury Marine. It is doubtful that Wolverine had the ability to copy the original masters. If you have doubts you can measure the cam. The original specs are:
.006”_____288º/296º
.050______231º/239º
.200”_____143º/147º
Lift Lobe____.3233”/.3280”
There was another version of this cam with slightly altered exhaust lobe. It was 296° at .006”, 239° at .050”and 151° at .200”, with a lobe lift of .3383 “ lobe.

I've got a pair in my Scarab and they're rated at 500 at the crank, 470 at the prop I believe.

I was curious how long they were even available from Merc? From what I was told, they were a pretty expensive upgrade during their time. I've been very happy with mine.
