I believe it was Rayler who was finding this out first hand. Also when gathering parts for my project, the tech at PAC advised against going with the beehives in my application. It is easy to see that a beehive would have some inherent advantages or they wouldn't be so prolific in the OEM performance applications, but maybe for higher lift, BBC applications they may not be the best. Any comments?

I think the answer to this would depend on what you define as "higher lift". If we're talking about .600" and above, then we might have a discussion on our hands. If we're under .600" lift, then there are a number of options available to consider in a beehive design. What it would really come down to is what the stress levels are in the application.

Crane HR's typically use .610 to.632" lift with 1.7 rockers. Mild mid 220 at .050" to 242 at .050 durations.

Can't remember the last cam I put in a big block with less than .600

yea, been wondering why I haven't seen the behives move into the big block world. In my SBC in my 64 Vette I run short travel hydraulic rollers, 240's/575 lift with 1.6 rockers, behives with titanium retainers - right up to 7,000 rpm. Maybe that's their limit on lift? even though I'm not running the highest rate ones... Although the LS motor guys (cars) are running crazy high lift numbers with them I thought?

I've only seen a few beehive springs in marine big blocks. And they've all been broken in short time.

Tim, what did you end up running for your final oil cooler thermostat setup? Also what are your ambient lake temps and what are you running for oil pans?

I didn't care for the temps I saw with the stats, so I removed them.

i run engine to collect and back again like I always did, see average of 150 ish after cooler max of 220 ever after miles of WOT.
pans are 12 qt

no water stats I average 130 water temps

water right now is 60 ish degrees
