before i throw the guy under the bus (Mikey), I bought the car from a good friend he had Mikey at Rapid motorsports install/tune the car and my friend swears it was a g5x3 he gave to Mikey to install. I have left messages and PM for mikey and have heard nothing back. I did not own the car when Mikey installed the cam so I want to make that clear.
The g5x3 is not those specs they are 600/610 lift and duration is not listed on there web site 2xx 2xx
P.S. I had a lifter go bad thats why I pulled the cam, lifter ruined the cam lobe

Well, if you simply going off the lift being different, 600 vs 589 isn't too big of a difference and 610 is very close to 612.
I bought a new TR224 and the cam doctor sheet that came with the cam listed the duration as 224.8i/225.1e and the website listed lift is .564/.564 but mine was .569/.568. So it's close, but not exact.
I'd try hitting up LG with some info and see what they say. I'm sure there's some kind of number on the cam that they can reference.

The G5X3 uses Comp Cam lobes 3727r intake and 3731r exhaust. That's advertised by Comp as a 234 duration intake with .600" lift, and 242 duration exhaust with .610" lift. Those numbers are usually wrong. A friend got a cam doctor report done on his before install and it came in at 236 intake and 243 exhaust. Lift was .598" intake and .612" exhaust.
You probably have a G5X3 cam there...

The end of my G5X4 looks like this...if you look close, you can see what's left of the Comp lobe # stamped at the bottom...most of it was ground away though.
