would yellow z06 springs be strong enough for a 220/220 112lsa or a 224/224 112lsa?

If not, suggestions?

 

whats the valve lift?

 

...and what lobes are they? (Comp XE, XER, etc.). I've read that the Comp XER lobes are very aggressive and require alot of seat pressure, more than the yellow springs have. If you're referring to the Thunder or TSP cams, I believe that they use Comp lobes and require something like Comp 918's, but I could be mistaken...

 

Right, like stated above it is the amount of lift and the ramp rate that determine what springs. The 918's are very popular.

 

if it is a thunder cam they say that the z06 springs do not have enough seat pressure and recommend the 918's.

 

Dont mess with the z06's. Get Comp 918's or Patriot golds..

 

I would stay away from 918s for now. Get anything else but those, unless they resolved their problems. I would install the LS6 springs before the 918s anyday just because mine failed. However, get what is specified maybe the Patriots, scoggin dickens, crane.

 

Comp had a recall of all the older springs and has replaced them with an upgraded version. I would not hesitate buying the 918's at all I run them. The new springs have no stripe and are shot peened to a nice bright finish. IMP Comp's customer service and products are top-notch!

Don't forget to allow aftermarket springs to warm up before you play hard

 

Wow, thanks for all the info so far guys. I'm not exactly which cam I want to go with, or the exact specs yet.

But as of right now it looks like I will be running the 918s unless something new and improved comes out by the time I get the cam. Should be within the next 6 months or so.

Any of our sponsors sell the 918s? Who has the best prices for them.

 

I ended up going with the springs that were recommended for my cam from the manufacturer so thats something if u dont wanna do 918s
