I would like to hear Brents comments on this.
Brent, what about hydraulics with beehives- still too heavy for 6300-6500 rpms on the FE?
If you can get your valvetrain to turn 6500 rpms with hydraulics, you can make good HP and have a maintenance free setup. A quality hydraulic lifter can take 150lbs on the seat and 400lbs open. This is easy for a SBF but like brent said FE, hhmmmm... I'm just not familiar with.

Almost any solid roller lifter is going to be pressure fed these days. However, there are different qualities of lifters...
I run hydraulic rollers with FE's and beehive springs. You still can't get the rpms up without extremely light valvetrain, short travel lifters, etc.
My hydraulic roller stuff, no matter what engine, usually gets at least 160-170 lbs seat pressure and 385-425 lbs open pressure. I use Morel lifters.
