A. springs that use factory retainers, keepers and locators

or

B. A kit that includes all of the above

.02, .200, and .300 numbers will tell the tale of spring requirements. What base circle?

Why does everyone automatically jump to the conclusion you can't run a 400#/in spring on a solid roller? Unless it's a lobe made for the high ratio stuff, they don't make many "valvetrain killers" with a .380 lobe

Like stated, spring choice depends on the rpm range and lobe being used. Max lift is just one part of the equation.

Two cams with identical duration and lift @ 50 can want very different springs if one is an old lazy lobe and one is a crazy aggressive one.

it's not that solid rollers NEED more pressure than a hydraulic roller. It's that if you float a solid roller lifter it will come apart a lot quicker, so it's usually more beneficial to over-spring them and lose a hp or two from the spring pressure, than blow up a lifter and grenade your motor. You can get a moderate solid roller to live with 160/450, and you can get a killer one to come apart at 400/1300. I've seen quite a few hydraulic roller lifters on solid roller lobes lately, and most of them are running about 400#/in, with more seat pressure to control bounce with the heavier lifters.

A hydrolic lifter wont last long with float either. I had a lobe start to come apart on my old gm846 cam, and with only 3-4k miles on my old bre cam the rollers on the lifters were already starting to pit.

a correctly set up valvetrain shouldn't lose control at any RPM in the engine's operating range, or at any level of engine acceleration. There's limits to the spring pressures you can run on a HR, and sometimes those limits are HIGHER that what a SR combination would talk. It's not all about spring pressure eitherl I'll bet I could get a 720 lift solid roller to work at 7000 rpm with 200/500 with some nasty lobes.

Just a simple test away... who's sponsoring the test?
