Recommended valve springs?

[kyles73dart]

I am looking on summit for valve springs for my 360 but I don't know which ones would be good for my setup. My cam is a relatively close to stock. Nothing extreme, just mild. I also have X heads. So what spec springs would be good for my engine? Thanks

You need the springs that the manufacturer of the cam says you need.

It is a summit racing camshaft, I think the lift is .441/.441 and duration is 276/288

Ok. Then use the springs they recommend.

901 comps would work on that.

Kyle 73,

That's the Summit K-6901
Lift ....................... .441"/.441"
Duration ................ 278*/288*
Duration @ .050" .... 218*/228"
LSA ....................... 114*

Performance Range > 1800 to 5500 RPM's

Close to the 'stock' 340 Hydraulic Camshaft.

The Mopar Performance {#P4120249} are 340 'stock' replacement Valve Springs

* Type ................ Heavy Single-Coil {.206" Wire} w/Damper
* Load Rate ........ #90 lbs. @ 1.68" {Installed Height}
* Load-rate ........ #240 lbs. @ 1.27" {Valve-Open}

Good for 6000 RPM's.
