Help with Cam Shaft Info?????? I'm trying to figure out what brand cam and details of it that is currently installed in my 99 camaro. On the end it has the following.
RRS1-231-231 UA7D 112
241820 (Is engraved in it) The 0 may actually be an 8 or 9.
Thanks for the help.

Edit: with a little googling, the 'RRS1-231-231' looks to be in the same format as Lunati grind numbers found on Summit. I cant find that specific grind number anywhere. Custom grind maybe?

Typically maybe, but I've seen plenty of turbo cams on 112s and with lower exhaust durations. It dependson what the motor needs. The LSA is just a number that comes from the valve events. With the info given we don't know the valve events. Just duration and LSA doesn't say enough in my opinion too say it's not a turbo cam. It might not be, but also it very well could be depending on the actual valve events.
Also, I'll throw it out there that longer exhaust durations might hurt spool times on a turbo. Hold that valve open to long and the exhaust gas velocity drops. I'd think you want to keep that exhaust gas hitting the turbo moving as fast as possible.
