Ok, had my heart set on the CC 306. Bought CC 986 dual springs, which is what CC reccomends for that cam. Well, I changed my mind on the cam. I'm going with this one instead...
239/245 duration, .577"/.576", 112lsa

What would be a good valve spring for that setup? I'm thinking the CC 987. I also heard the CC 978 is a good spring. The 987 is a little cheaper though, so I'd rather go with that. Would it work? How about the 978?

Hopefully my machine shop will let me exchange the springs I already bought... If not, anybody lookin' for a set of 986's?

 

I guess you guys have just as hard a time finding specs on springs as I do. Dang! Comp cams website isnt' any help either....

 

Im lookin for a set.....

 

hey man, do you have AIM? we can talk about that stuff, im a comp dealer.

The 987-16's should work well i believe they are good to about .600 lift or so

 

since you didnt hit me up on AIM. the 987is good for your cam. But if i were you id opt for a set of 26918's which is comps new reccomended spring for the CC306.
