Fast rate hyd cam = won’t rev.
That’s your mechanical rev limiter.
Especially with what’s out there for hyd lifters these days.
A SFT is really a much better match for something that has the potential to run at higher rpm.
That cam would make decent power, up to the rpm limit imposed by the lifters.
Do you think the cam is solely to blame for the poor top end?
Not so much the cam, as the lifters........ but the fast rate cam will find the limit of the lifters sooner than a cam with long slow lobes.
Pull a couple of springs, measure the installed height, and have them tested.
If they are 125-135 closed, 300-340 open...... they’re not your problem.
