Comp beehive spring installed height Qs
I am very excited that according to Carcraft i can drop in a set of comp 26918 or 26915 beehive springs into my vortec casting an instantly have 0.550" lift capabilities. I order to determine which springs best suit a GM lt4 HOT cam i need to know the height they will be installed at. I know that the stock vortec springs have a 1.700" installed height, but i am unsure if the behive retainers will change that (the 0.100 extra lift has to come from somewhere).
So i was wondering if anyone has used beehives in the past? Will the beehive specific retainers (comp 787) change the installed height realtive to the stock vortec retainers?

Re: Comp beehive spring installed height Qs
I have 26918 springs installed on my Vortecs.
Installed height; 1.820".
I've also had the heads machined for screw in studs and guide plates. The 1.6 Pro Magnum non guided rockers required the pushrods holes to be elongated as well.

Re: Comp beehive spring installed height Qs
thanks skinny, do you have stock length valves? If so thats good news, i won't have to hunt around for +0.100 valves.

Original valves. Except for one which I bent during a missed shift. (7000+)

You can also use Manley 22410-16 springs, 23652-16 retainers and get .550" lift with Vortec heads. They're not beehives but they might be less expensive. I used them just fine with my Corvette heads and LT4 hot cam.

Link to Car Craft please. I have installed '918s and ARP 134-7101 studs. I know theres an increase in available lift, but I had no idea it was that much. If thats the case, that opens all kinds of doors for cam selection.

Re: Comp beehive spring installed height Qs
I got a package deal from comp themselves and run the 26918 beehives at 1.800 installed height and run an extreme fuel cam.....576./.571 lift and they work great...so those springs can handle over .550 lift....they are good to .600 lift according to comps web site!! http://www.compperformancegroupstore...&Category_Code=
