is a spring a spring?
 

here i go, what seems to be the best valve spring set up for a 1999 hp500 sr.#OL600036? i've heard from some to use comp cams 929-16 with 99961-16 crane retainers and 99098-1 crane locks. others say only use isky 8005a springs and the stock retainers and locks. the specs on the springs show different seat pressures and pound rates. is a spring just a spring????????

thanks sutphen30 i'll go with the iskys. is there a better retainer than the crane 99961-16? 10 degree locks are better than 7, right? i've also heard talk about viton seals, where can i find them? thanks again.

Vitons seal too good. Boat needs to pull a little oil into the guide. Yeah, teflon is good.

I deciede to get the 929's for my 500 EFI. The question is, can I re-use the stock (Crane?) retainers and locks or do they need to be replaced at the same time?

Half my gear head friends say I must get Ti retainers and the other half say they make no difference @5400.

A hundred bucks is a hundred bucks but I don't want any problems later on.

THANKS!!!!!

I have 270 hours on them.

Do the super 7 degree locks fit the same steel retainers?

Check out Comp Cams new 26120 springs and technology. These springs will do everything the cam in the HP500 needs and with the smaller valve system mass thay won't beat the hell out of the lifter pins, which are the weakest link in the big block valve system.
Check it out!

I just had my heads gone through - 250 hours on a blower motor. The springs were good (Isky 8005A), so I bought another set for a third set of heads I'm building. I bought them from Flatlander Racing, and they recommended the Titanium retainers and 10 degree locks. This is also what my engine shop recommended, so that's what I went with.

Hey Steve,

Post some new pics of your Cafe re-fresh!!!

Good to see you in Miami!!!!

Always a pleasure to see you also.

Nothing new to post right now. I'm doing my garage work right now like putting engines together, painting parts, buffing blowers, etc. March will be my prime "bolting-on" month. I'm still targeting April 1 for launch, but not sure if I'll make it.

hey raylar, have you or someone else used those beehive springs #26120-16? 155lbs on seat at 1.880" , 377lbs open, and 370 rate. seems pretty good for not being a dual spring.
