Comp Cams Beehive Springs?

I used these Beehives first, they were the earlier ones and they were terrible from the start with the XFI lobes.

Then I upgraded to the latest, greatest Beehives and they are the ones that worked OK at first but soon died. These were the ones that appeared to be peened or shot blasted.

Here's the new engine, LT4 with a solid roller/ 12:1/ and it's been running at the top end of the Optispark's limits in my Impala. I don't expect it to float a valve. This one should be making about 550 crank horsepower and I'm going to put it in a 95 Corvette ragtop that I just bought in December. Waiting on headers and a torque converter. The old 420 RWHP hydraulic engine is going back in the Impala. The LT4 engine has the LT4/LE3 heads (215 cc) and doesn't have the torque of the old hydraulic engine. I've not had it on a dyno but I know the torque isn't as good as the old LE2 engine. It will have more than enough torque for a 3300# Vette but the 4400# Impala wants more.

No more Opti, what a shame.

Again, I've been there and done what you are going to attempt. The Beehives worked well for a while and maybe the folks that didn't have trouble with them were not running the dog snot out of them on a regular basis. I revved to 6500+ with that engine, maybe they didn't. If your going to expect to see 7000 RPM definately get a dyno tune and keep an eye on them. I threw them in the trashcan and wouldn't even sell them on E-bay. I couldn't screw someone like that. Good luck with your build and be ready to wear the biggest grin you've ever had.

what kind of rockers are u running? Those look nice

hey Dangalla are you runnung the PAC Racing 1218 Ovate-wire Beehive Springs? cause thats what im running and i have a 576 lift and they work just fine with no issues.

[Dangalla]

i just noticed that while he states that they are behive springs, the number he lists are not a behive spring

1963SS if you were going by the number and not the behive statement i apologize, i should have looked closer. but by your statements i dont think that is the case because you specifically state behive springs

ta the destroyer, yes i am running the 918's with 600 lift and only 230 duration, been working great for me, as long as they are set up with the correct installed spring height they are a very good and very widely used spring

OP you need to figure out what you really have, if they are really behives (26918) then you should be ok, but if not i would not run those

thats what A.I recommend that i use and they have work just fine for me.
