I currently just vent both valve covers to a catch can, but since I have the motor out I was wonder if adding an LS6 valley would be worth it to help vent more? I have a T76/81AR and am going to try and get as much boost as I can.

your vent system should work, but you should have some vacume sucking in the catch can. I hooked my catch can up to the inlet on the turbo so it creates vacume.

Can you swap that .81 for a .96?

mike do you really think he needs to swap to the .96 since his is a rearmounted sts? He might have the correct ar?? I just know the rearmounts have a hard time spooling so they are run lower ar's than front mounts.

Didn't realize it was a rearmount. Backpressure will be high either way then.

Edit: Yikes! A 408 with a T-76 rearmount .81 A/R. Backpressure will be through the roof!

A LS6 valley won't hurt.

i would get the ls6 valley...408 running more boost...a lil extra way to relieve engine pressure

I'm running total seal rings, it has pretty much eliminated any pressurization of the crank case I was getting.
