why would you want to run a hyd profile on a solid lobe and as alan said it would be a guess my blanks should be at the grinder

idk..lol Im not too savvy on internal stuff, trying to learn, I was just asking for a good general guess for comparison sake out of curiosity. Your guess would be better than most.

my bad I meant can you instead of you can on my earlier post. was a question

How exactly are they different, thats my big question? Is the material different? Is the ramp angle changed? etc

At what point does this become an issue?
Is it an issue with stock cams/springs/lifters or s1 or s2. I think I now understand the problem and vaguely understand the solution but cant figure out if its always an issue with the ecotec and the cams/springs make it worse or if a certain set-up causes the issue

any boost over 18psi will start collapsing the lash adjusters stiffer valve springs will lower the thresh hold for the collapsing point bigger cams with an increased rate of lift will also affect things

To all the people asking questions between Hydraulic and Solid lifters:

COMP Cams® - Lifter Technical Reference




As for power gains, it's tough to say, I'm not sure there's been anybody that's actually run a solid lifter..... but having said that, upgrading from cams normally make a pretty decent difference on worked over motors in general (IE: ported head, bigger SC than stock, etc etc).

the race teams run them and they are used in other platforms with no problems

Oh yeah solid lifters aren't a new idea by any means.
Didn't the Honda B series motors use solid lifters (I know they had to get lash adjusted every so often and had lifter tick issues)....

That's one of the nice things about our head; once assembled, the only way it would ever need adjustment would be if something is mechanically failing. Such as valve seat sinking, stem mushrooming, rocker wearing out, etc. there is simply nothing to move.

Nice read and glad something has been figured out as to the lack luster gains from our current builds and cams selection.

This makes me glad I'm still on the stock head and waited patiently to build a nice ported head with the right internals in it.

So solids and cams with ported head and bigger exhaust valves would be a nice combo to use.

Well crap guess I fit into the, 'My lash adjusters are gonna collapse on me soon bus...'

I get buying custom ground cams, but where do they offer solids?

Poorly worded question on my part but you answered it - Mr.B's using Jesel parts and you're using Bates, but they're both solid lifters.

Can't wait to see the results!

How often are you expecting to have to adjust the valvetrain? Im assuming this is a big no no for daily cars?
