well i was just wondering if the comp 986 springs will work on a 306, with 1.6, ithink thats adds up to 580 lift on the exhaust.

if someone could tell me i would appreciate it.

 

I am running that combo with no problems.

 

thanks thats great. how fast are you spinning it up to.

 

6500rpm at the track only, my timing chain is a stock replacement.

 

i see in your sig your running the cc306 the one im refeing to is the cs306on a 10 it two differnet cams the one im talking about is a solid roller cam.

here is the spec sheet on it

and here are the lobe differences in the lobes

scroll to the bottom of the page the cs306 is a solid roller and i would think it has to have a stronger spring.

the red red shows a cc306 and the yellow chart shows the cs306.

but anyway how do like the 306, does it sound good ive never heard one in person just sound clips, and thats not much.

i would really like to know what youthink of your cam.

 

It says at the bottom of the spec sheet that the 986 is the recommmended spring.
