If I decide to go with Crower lifters what is the comparable part number to the Comp 857? Is it wise to use the Comp cam and the Crower lifter combination?

I mix match brands all the time. Flat tappet Comp or Melling with Johnson flat tappet lifters, and different brand hydraulic rollers with other brand hydraulic roller lifters. There are no real issues with doing that. It's more about buying the quality parts that work.

Like Steve mentioned, other than possibly pushrod length changing for the different brand hydraulic rollers used.

Why are you changing the transmission?

I ask because you've never mentioned the failure of the trans pump.

If the trans pump isn't trashed, the converter didn't balloon. It might have pushed forward due to excessive fluid pressure in the cooler circuit, though. That could wipe the thrust bearing on the crank, but not damage the trans pump.

Any chance this build had a crappy Eagle thrust face on the crank when it was assembled? They were known for that problem years ago. I'm told that's been taken-care-of since then.
