470 going to the dyno - HP/TQ estimates

Just a couple updates. Scott Koffel and I talked this morning when I dropped off the motor. He seems to be easy to deal with and knows what he is talking about. That being said, I am more concerned than ever about the hydraulic roller lifters. Mine are Trickflows purchased on 2021, so I believe are actually Morels. Scott relayed that they have had issues with hydraulic roller lifters on the dyno, but not the instability issues that others have mentioned. Basically lifter plunges getting stuck due mainly to tolerance issues with the lifters. He said this was mainly with comp hydraulic roller lifters, so I am keeping my fingers crossed that I won't have this issue. Motor should be ready for some pulls tomorrow.

If they are Morels you have a much better chance of success. Were they disassembled, inspected, cleaned and reassembled prior to being put in use?

Just a little reassurance maybe, the hydraulic roller lifters in my BBC were dead stable to 6700 on the dyno, and while I dont turn it that hard in the boat, it has been to 6200 many times. They are factory gm replacement hydraulic lifters. Good oil control and pressure is important.
