I'll have to get some pics of the valve covers this weekend. My camera is at a friends house. Truck feels way stronger on the bottom end. Top end is about the same as the 5.3 with timing and meth, maybe a bit stronger. Should be fun with another 4° of timing

Just put the S465 on it. That's how it's going to stay. Those pics show the size comparison between the two, 1.32AR exhaust housing with a 96mm turbine exducer on the 75, and a 1.10AR with an 83mm exducer on the 65. The 65 makes boost way sooner. I can actually roll into it in OD and almost get full boost Also a pic of the near-hidden valve covers. Wiring could use a little tidying-up, and it would look good with a coilpack relocate...we'll see.
I did lose about 2psi of boost, presumably because the exhaust side is smaller on the 65. Only gets 8psi on a 12psi spring I'm going to check in the morning to verify the quick spool isn't getting hung up. If it isn't, I may just have to swap in the lighter spring and pull the boost reference off of the WG. Maybe see about 11psi then.
