Are there any that fit Buick yet? Anybody have any experience with these? Sounds pretty good if you believe the ads. Looks like a chevy deal at this point though.
I've heard that those will only work with smaller valves, not the valves in a BBB, especially Stage 1 valves.
Just found this on the CartCraft website; http://www.carcraft.com/techarticles/116_0402_spring/index1.html
Valve stems Generally they use the on 11/32" valve stems so I don't know how the retainers cross over since stock Stg 1 is 3/8". I think they would work great on just about any hydraulic and some of the mechanicals. I know I would definitely look into it if I could use them.
The beehive springs work quite well on the LSx engines.....keep in mind, those guys have those heavy hyd. roller lifters to contend with. They routinely rev those engines much higher than most anyone on this board!! There are quite a few applications for a SBC. Also, keep in mind...some SBC's had 3/8" exh. stems. You should be able to get retainer for the beehive springs in a 3/8" setup. Not to mention, the BBC has a 3/8" stem too. SBC valve springs are very close to the OD and overall height that we use on our Buicks. They can be had from the stock 1.25" OD to 1.550"OD. Height wise, from an installed height of 1.700" to 1.900". One of the more common double spring sizes for the SBC is a 1.430" OD and installed height of 1.800". Check out the beehives that Comp Cams has.....I'm sure others offer similar springs.
Sounds like you spin it pretty good too!! :TU: I'd look for a Titanium retainer for an application such as yours. Between that, and the beehive springs - that should make a difference. You're right about the valve weights.....of course, their hyd. roller lifters are substantially heavier - should even things out pretty close. What pressures are you currently running?
