With the Beehive springs and steel retainers, the engine pulled to 6300 RPM with no other changes.

To date, I can only remember ever seeing one broken Beehive spring, and I believe it was the victim of other parts failures, not the spring itself.

Paul, Does that mean one wouldn't have to spend the extra money on a tit retainer then if using the beehives? I meant 1.800 IH since it coil binds at 1.100 in my post above. I think I will run some tool steel retainers, there lighter than the moly ones and only a little heavier than tit and half the price!

The Ti retainers are nice, but the steel retainers for Beehive springs are very small and much lighter than the steel retainer for a conventional spring. The steel retainer for a Beehive spring, I would say, is pretty close to the same weight as a Ti retainer for a conventional spring.

Also, I failed to mention that the Beehive spring setup was about 10 lbs. less on the seat, and IIRC, about 350 over the nose.

Yes. I forget the number, but it was the big one for BB Chevy. I believe it is the biggest/strongest available from them.

The only one that looks close to your 350 open is the 26120 with 388 open, 370 rate and a 1.900 IH @148, I like that one too, but its only good for 600 lift which would work for me since I run just under that with lash, but no room to grow in lift.
