Ah thanks that's good to know. I think I know what to do about oiling though: kickout oil pan and better (vertical) air-oil separators over each head vent. The stock 6.1 (horizontal) AoS in the intake manifold turned my catch can into an oil grenade once I exceeded about 1.1 g.

Maybe I'm too used to LS stuff but 0.650" sounds plenty to me; that's about what LS7 rockers max out at too. I need to take it easy on the valvetrain anyway, so things stay together on the road course. I'm surprised these motors like so much valve lift given how well the heads flow at lower lifts.

I'm running modified isky High seat solid lifters , use to have the PQX roller tip rockers but switched over to the Harland sharp about a month back. Heads are a set of Highly modified Eagles with 2.165 x 6mm intake valve and 1.63 X 7mm.Intake is a Edelbrock Victor with the runners cut down.

What are you doing for engine management to make that big cam drivable?

Since I'm running a smaller CI G3 I'm able to use the stock ECU/PCM, it doesn't like 7500+ RPMs that's where we have issues with with this truck, My Brother had to switch to a Haltech in his 09 Ram , the OEM stuff couldn't handle 460ci G3 spinning above 8k let alone
