Does my cam look worn? Should I change it?
Discussion
Thanks guys! My 450's cam is showing early signs of wear, according to the last dyno run I had (and I'll be having another soon to monitor how quickly the wear is progressing).
So I'm starting to ponder what I'll put in there. It has developed very good numbers on SRR's rollers: 276 bhp about 4 years ago, and 265 bhp about a year ago. So I don't want to lose power, but at the same time the very last thing I want is to lose my engine's very well-mannered driving characteristics: no shunting at all.
Is there any risk of a well-mannered engine developing a shunting habit if putting a stealth cam in, for example? I have read opinions that the 14CUX struggles with longer duration cams.
Also, I notice from the V8D web site that both the MC1 and Stealth are recommended to be fitted with double valve springs, which I don't believe a standard 450 would have. Is that correct, and to what extent does it matter?

Thanks Peter. It will be very interesting to find out what cam the engine currently has, because its bhp figures imply it may not be as standard as I thought. There's nothing in the history file to say it's already had a replacement; maybe it had something different straight from the factory?
