If you are planning on going to 8k very often i would recommend getting some aftermarket springs(supertech or somthing), stock redline is 7200 i think, but i wouldnt spend the money on new retainers.

What I've heard over and over again is that if you are upgrading to a cam of this nature you should upgrade the springs because stockers were not designed for such rapid and extreme ramp rates. And If you are going too much over redline get some retainers. I was told this be the owner of Delta cams, he's a really nice dude, call him up and talk about your setup and he might have some helpful insight or even some info.

I'll be running a Z6 272-2 with crower springs and probably stock retainers.

I recently made a similar thread, as I was considering running my 272-2 with the stock springs being that I'm a fucking cheap bastard.. :bandito: >Stock springs+aftermarket cam< Some guy mentioned doubling up the exh side IIRC. IDK, honestly I'm still considering. Iknow, springs are cheap.. but so am I!!:ph34r:

for peace of mind spending another $125 on springs is well worth it.
and you can rev it alot more safely if needed

Very true. What spring do you reccomend in that price range? And thats running stock retainers right

It depends on where your power band is, but as long as you stay under stock redline there is no need to upgrade
This is not true. The upgraded springs are because the cam has more lift.. the factory spring MAY bind at full lift. Also at WOT at high RPM you are subject to valve float. Springs should be upgraded IMO.

I run Supertech.

Like I said....I run a hx35.....you want/ need hose extra rpms to open up your powerband......5500-7200rpms didn't seem like enough....and in reality is not.....letting my motor wind out makes a huge difference in the way the car feels/pulls

^^ This.

When running a more agressive cam, the valve spring rate has a lot more to do with the ramp rate, lift, duration of the new cam. The factory spings just weren't made to handle that. RPM is just one factor in the whole equation.
Honestly, after building v8s for so long, I couldn't believe how soft these Honda springs are. Even the aftermarket ones feel soft to me.
