@34:00 I just commented on Steve Morris's video about the LS that was rolling over at 6800 that he might want to look into a Spintron. I understand that's not cheap. The problem he had with hydraulics on the engine were cured with solid lifters. What would be cool is a dynamic testing apparatus that was kind of like a spintron in that it would moved the lifter at different speeds to see where the lifter started bleeding or got pumped up, check the pushrod loads and displacement, etc.
Daniel, Merry Christmas to you and your family. I hope you have a great Christmas, cherish your time with family and enjoy every precious minute. God Bless you all.
Im with you on an educated guess, there are just to many variables.. Remember Eric was a teacher for many years before he went full time porting heads.. That how he did so well on the podium.. I hope to buy a cam from you soon..
I can also remember tightening the intake and backing off the exhaust to test advancing and retarding the cam timing if it was too bloody hard to re time the cam . Good enough for testing purposes. Not good enough to run.
Merry Christmas Daniel Powell oh hey I got a question that I just thought of in my head and maybe for a while I was thinking about this with hydraulic lifters. Now my question is is it possible with a hydraulic lift camshaft the lifter being hydraulic is it possible that the plunder could collapse some being hydraulic so you may not get to full lift and duration as advertised which I know it goes back to at the valve thing with solids with lash but would that be a similar case with the plunder that could collapse some and loose some lift and duration or am I way out of the part wrong I am just curious because I thought the hydraulic was designed when parts wear it would plunge down a little so you don't have to re adjust valve so it made me curious when the valve open if it has room to plunge down would it loose some lift again I am just curious if I am way wrong let me know I am learning as I go and trying to learn off you and others for sure because I am just learning engine as I go and I race wingless spec sprint car and all I am doing and learning as much as I can
Share your same interests and questions. Currently trying to dial in 13 degree na sbc to make happy above 7200 rpm. Currently 421ci, 1.7 T&D rocker, going to standard base circle cam (.450/.430, 281/287@.050 on a 112), titanium valves, .903 lifters from .842, 7/16 dual taper pushrods and wondering seat pressure for springs (285, 308 vs330)? Open pressures vary from 765-940. Any tips appreciated
I am so pleased that you and Eric work together so well, you both have the best, most informative channels and respect you both.
We really appreciate that!

Yep, a spintron will answer those questions
Thank. Merry Christmas to you.
Same to you!
Merry Christmas ❤
God bless you all 😊

Daniel, Merry Christmas to you and your family. I hope you have a great Christmas, cherish your time with family and enjoy every precious minute. God Bless you all.
Thanks, you too!
Thanks for the video!
You bet!
Merry Christmas have a happy New Year
Ty sir

Awesome, ty
Lol Eric a teacher! No wonder he made a career change!
Merry Christmas and happy New Year !!!
Ty sir!

Definitely
Happy holidays brother
Same to you

Absolutely, a high leakage rate or the check ball not sealing can create this issue 100%
@PowellCams got it thank you

What's the opening/ closing and peak vel/acc #s on the lobe?
I remember solids with more lash in the old days that showed advertised dur. at . 016 or 017 to give a closer idea of what the lobe is actually doing.
I don't think I've ever seen anyone rate a solid at anything but .020.
