Default Steam vent for LS7 MSD Atonic Airforce

What steam vent set up is recommended for a Gen IV block with an MSD Atomic Airforce intake?

I reused the same vent tube I had for my LS3 FAST LSX-R which I think was an LS6 style that I bent slightly to clear the underside of a Nick Williams 102 cable throttle body.

I don't know if you have sorted out the PCV tube yet? I had to use the GM molded LS6 tube. The plastic LS3 will not snap to the intake. Don't use bulk auto store tube; the bend radius is too tight and it will collapse with use.

Thanks for the input on the PVC. I will add an LS6 tube to the parts list.

Just an thought on the steam vent line. Which ever one you use I don't care for using a rubber line to the radiator. So on the vent tube I cut the discharge nipple off and drill and tap it for a 1/8" pipe thread. Then use -3 SS line to the radiator using -3 fittings as needed.
