I had a 212/218, ls6 intake, along with the whole 941 spring setup, titanium retainers, etc for a year. I swapped the 212/218 junk cam to the TR224 cam and a Holley intake. My question.. is it safe to be running this cam with the 941 springs? I know now they use the new 918's.
My 941's have been in there for a year with zero problems. Maybe I got a good set?

Jeremy,
I was in the same situation as you. I decided to just keep them in there. I have had these springs for a lil over 10K miles with no problems to report. Some of us got good batches <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Yes you can do it... i dont recommend it. But if all works well you CAN do it.
The TR224 has some pretty aggersive ramps. I would recommend nothing less than the 918's... but, if you get them packaged together and are stuck with the 941's... go for it.
Good luck.

941's are a ticking timebomb....period. I know people say "Well, I've been running mine for xx,xxx miles with no problems." Congrats...that only means that with every passing mile/day you're getting closer to breaking one.
Believe me, I was one of the guys that said the EXACT same thing. It seemed like everyone was breaking them left and right, but mine (with 13K miles on them) were chugging right along with NO problems. I always said, "I guess I got some of the good batch. Not only that, but I'm running a small cam (218-224 / .525-.528), so I'm sure they'll be fine" . WRONG! I was coming home from Dinner one night with my wife....just cruising along about 65 mph, when one of them broke. No biggy...I replaced it. 2 weeks later, on the way home from work, I broke 2 more!....again during normal driving conditions. Not long after that I decided to swap my heads. When I pulled, them I immediately noticed "smiley faces" on several of my pistons, where there had been some valve/piston contact. Many of the smiley faces were on cylinders that DID NOT HAVE BROKEN 941 SPRINGS. That tells me that several other 941's were weakening and about to break! As I said...they are ticking time bombs.
If thinking that your 941's won't break, will help you sleep...go right ahead. But sleep tight, because when they break, you're gonna need all of your energy to repair the damage.
For your sake I really hope I'm wrong....but I'd bet $$ that it's only a matter of time (especially w/ the 224 cam!)

But don't I read about 918's breaking? What's the deal with LS1 valvesprings?
You can get the most agressive cam in the world for a 5.0, matching valvesprings, and the damn things will NEVER break.
Now you guys are scaring me though.

Jeremy,
I would stick with your 941's. Its not like the 918's are flawless. I remember a few people posting about busting those springs too. The point is is that with these aftermarket cams, aftermarket springs, extra stress..stuff is going to break from time to time period. If you feel nervous about it, then just buy the 918's. I dont think they cost too much. Im stickin with my 941's for another few thousand miles <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

The 918s are very good springs and they are a lot better than 941s. But a few guys have reported breaking 918s, to be on the safe side go with a dual spring. If one of those breaks the second spring will keep the valve from hitting the piston.

The one good thing about 941's is that you can buy replacements for about .25 each (still about 5 times what they're worth). <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
Good luck!

I ran the 941s for about 7k miles and they held up great. I always made sure to let the car heat up before taking it above 2500rpm. I have since switched to Comp 987 dual springs.

Well, after 30,000 miles on my motor, my 941's finally broke. I was was running comp cams 525/532 lift with 216/220 duration. I use my car for patrol and today it finally broke. Will be replacing them on Monday, but dont know what springs to use until I redo my heads in couple of months. My friend has the ls6 springs but recommends using the 981's for now until I redo heads.

I would replace the springs, for several reasons:
*they have a good amount of mileage on them
*new cam will have more aggressive lobes and be more demanding of the spring
*your looking at spending a few hundred to do it right vs spending a few thousand to clean up the mess if one (or more) of the old 941's break
just .02 worth
