I have been in contact with everyone but Bob since the beginning of this mess, so many guys trying to help and I appreciate it, part that comes with that is many opinions and some are factual and some not, my fact is I have wear, and 170 pages in I still see it as the cam specs so far, not sure 100% if that's cause it not but that's why seems to be the same.
Why does GM factory gen6 use as a wheel? They seem to go 1000 hours no issues but also I know cam spec plays a role, but how much load difference is there really?

What exactly do you not like me? I love it guys hate me because I must have spoken some sort of fact they didn't like at some point..
Your right something is off and pretty much everything's going to change too...

Everything needs to be looked at. The entire valve train from cam to lifters, to rockers, to springs. Something is off and so far there isn't one absolutely common denominator yet. Some from madara, as mentioned earlier some from crane? I think. Some with johnsons. Any with morels? How about .842 vs .910? How about geometry? I'm not saying it's one persons thing or another. You're not the only with the issue and as much as I don't like you I ahte to see anyone go through this bull****.

The .750 wheel will handle a higher acceleration rate than a .700 wheel. Most of the "modern lobes" we are using these days have much faster acceleration rates. You can have two cams with 240* .700" lift. They can have very different acceleration rates. The more acceleration you have in the lobe the larger the wheel you need. The larger wheel acts like a gear reduction...

me not liking you is irrelevant in this thread. Trust me there is no "fact" you've said that i disapprove of. If anything you're the most opinionated Widget out there. Either way cam specs was looking like the answer until people started showing other cams doing it. Not bobbys goofy grinds but from what I understood off the shelf grinds. These would be grinds tested on a spintron not on Bobbys kitchen table.
Ultimately I think there will be no concrete answer and it will be left up to whoever reads to figure out what they think went wrong.

Havoc40/ Randy, what spring pressure is the 2126 lifter designed to sustain? That seems to be absent from the website. Thanks. Edit- is it possible to categorize it, could you say xxx lbs should be good indefinitely, xxx lbs should be checked/ replaced after a certain time, xxx lbs shouldn't be used at all etc ? Thanks
