turbo_Ls4

**possible sticky****
met up with will overkill for burgers and tuning ( a friends car ) and we talked about cams
just in case anyone didn't know any 2005-2006 LS4 can use a LS9 cam
P/N 12638427.

the 2005-06 ls4's use 3 bolt cam gear which the ls9 cam is.

the 2007+ is you use this part P/N 12586481 it will give you a 3 bolt came gear- or a ls3 cam is a single bolt cam



in the 07+ ls4's use the Ls3 tensioner which has been proven less durable then the older ls2 style that the 05-06 ls4 use's. its not recomended to swith with newer ls4s but is an inexpensive part if you wanted to

LS9 cam is great for folks like yourself that are running a turbo LS4 or any other FI LS motor.

For N/A, I'd still get a custom grind from Jim @ CalSpeed or Patrick G.
