dual spring vs beehive
dual spring vs beehive Im putting together a parts list for my cc503 swap and im second guessing my spring choice (PAC 1218/1518).
Ive helped a few of my LS1 buddies do cam swaps and they have all used dual springs instead of the beehives im looking at. All of their cars dont seem to mind 6800 rpm one bit.
Is there a benefit to dual springs? I want a SOLID valvetrain, im not cheaping on stuff. I want a valvetrain than can take 7k rpms, even though i dont plan to spin my stock bottom end that high. I want every bit of reliability and power i can get. That being said ive read that beehives rev better because of their light weight and spring dynamics. opinions?

well ill get this out of the way and say EVERYTHING mechanical is prone to failure, which im sure you know. I would personally run the Crane 10308-1 springs with your setup, as im running the same springs w/ my 847 cam and take it to 6800 rpms no problem.

The PAC beehive springs are a quality spring. People have been using the Comp 10308s because they're a less expensive alternative to the PAC Spring.

If you're a little worried (nothing wrong with 1218s though) step up to the PAC-1518. The nitriding really does make it a much better spring and it's worth the extra $$$. It basically makes a good spring great. Better fatigue life, less load loss. Easily the nicest beehive on the market with PSI's being a close second.

IMHO the reason to run dual springs is if one of them breaks you will most likely not eat a valve. Now as was stated the beehive has less mass and better harmonics than the dual springs.
Beehives do not require the seat pressure or the over the nose pressure that a dual spring does. So less wear and tear on your valvetrain with beehives. IMHO with the quality beehive springs out there the chance of breaking a spring is pretty remote. Heck GM runs them on there performance motors now and they have waranty them.

I'm going on my 13th year with a custom dual spring set from Lingenfelter...They are actually on sale now for $69/set! You still have to buy the retainers, though....I use titanium retainers also from LPE...They are will definitely handle the CC503 and are very durable...
Definitely worth a call...LPE got its reputaion for going fast and being extremely durable...
