I have a quick camshaft question. I will be running a forged 6.0l ly6 motor with a turbonetics 7675 billet ball bearing turbo. I have cnc ported ls3 heads on there now. Shooting for an 11 to 1 with compression with Meth. I currently am running a 219/230 .607. 604 117lsa comp camshaft (thunder racing v3 cheatr cam). I was thinking about going to a livernois stage 2c high lift camshaft which they advertise as a 224/236 .646. 646 117lsa. With this set up would the extra duration and lift help much?

Can your head/valve/spring/piston combo handle that lift without fear of PTV contact ??

Why are you going so big on the cam side with that big of a motor and that turbo? I could be wrong but I feel like you will run out of turbo long before you need a cam that big.

I wouldnt spend the money, the 75 turbine will benefit from a narrower rev range

Piston to valve clearance won't be a problem as the wiseco will have valve reliefs. I spoke with livernois and they said the turbos favor a little more exhaust... I've seen some builds where the exhaust duration being longer helped to decrease back pressure on the turbo. I was still hearing people complain about high backpressure on the 6.0L builds even with the 75mm exhaust wheel. So I didn't know if it would help at all after selling my existing cam the extra 200 to 250 won't break the bank but just wanted to know if it was worth any gains

I always like smaller cams in turbo motors. Easier to drive, easier to tune. I wouldn't change it out. Hell my GTO went 145mph in the 1/4 mile at 4100lbs with a 75mm turbine and OEM LS6 cam.
