Well, its almost time for me to get out of the navy and since I won't be pulling in as much money as before so I want to make the car as reliable as possible without going back to a stock cam. I want to swap to a cam that I can run with LS6 springs so I won't have to worry about swapping springs every 15-20k miles or possibly breaking one. Right now I'm running an F-13 and Manley duals that have been on the car for, believe it or not, 30k miles. What do you guys think would be best for LS6 springs? Should I go hot cam, asa cam or possibly something custom. I know some people have talked about the TR224 with LS6 springs but that's pushing the limit of their max lift. So, what are all of your thoughts?

You can use any of the small Comp Cams such as 212/218, 216/220 and the COMP LS6 Street Replacement Cam with the LS6 Springs. They are made in Germany from the good stuff and GM says they will go 100K miles. I have the 216/220.
GM uses them on cams up to .570 lift.

ASA or Hot Cam

Geez Louise! Have the cam speced for the performance and reliability you want and use a spring that works with the cam. Don't do it the other way around! Chose your cam guy carefully and tell him what your goals are.

Thanks for your service, Navy! You help keep us free.

Thanks for your support.

I'll probably talk to Pat G about spec'ing me a custom cam but if I happen to come across an ASA cam cheap on the boards I might just have to pick it up.

why are you getting rid of your f13 cam? I have an asa cam and was thinking of going with the f13 or f14, but some people tell me its not much of a difference and just to go bigger but I daily drive my car

I'm definitely happy with the F13 but now that I'll be a college student I don't want to risk my DD being broke down because I snapped a spring. I figure if I get a lower lift cam I can run LS6 springs that were designed for reliability and longevity. Also, I'll be able to rev it slightly lower with an ASA or similar cam. My buddy has an ASA cam in his TA and it made almost as much power as my F13.

I'm running LS6 springs with my ASA fwiw

I'm running a 210/230 .550/.559 112LSA on stock LS2 Springs

Thank God you're safe and thank you for your service.

But, if I may, Just buy a new set of PP Gold springs, there is much higher chance of a single beehive to destroy your motor than a strong dual on a F13

So then you think I'd be better off just staying with the F13 and duals springs (I've got a new set of Manleys waiting to be installed at home) as opposed to swapping to a smaller cam and running the LS6 springs?

Maybe I'll just lower my shift light a little.

Yeah, stay F13 with good springs.
it's cheaper to swap springs than to do cams.

And you have to figure in retuning it too

TopFlite

Something with .600 lift or less because thats all the stock LS6 springs are good to.

.580 max if 02+,

I don't know why people think LS6 springs don't break. I've seen 3 broken ones on 3 different bone stock Z06 Vettes.

I ran my PRC dual springs on a 233/233 .598/.598 112 LSA cam for 44,000 miles and they were still good when I replaced them...I have 28,000 miles on the next set at this time and I will not replace them till at least 45,000..call the guys at TSP and ask them how many miles they put on the springs in their personal cars..a good set of PRC dual springs or Patriot dual springs are not expensive at all..changing springs at the low miles that you are talking is silly and a waste time and money .. If you have a question about your springs condition pull one intake and one exhaust and test them ...

PS I work at a Chevy dealership and we get a lot of Vettes serviced here and I have seen a number of broken valve springs on LS1 and LS6 engines and recently even LS7 engines .... I run dual springs on anything that I care about...after 40+ years of hot rodding I have never droped a valve on a engine with dual springs...I have broken two springs over the years but never droped the valve because one of the springs was always still good.

The beehive is a better spring harmonically then a dual...The LS6 springs have there place and that is on a mild lobe,there is nothing wrong with running them under 560 lift.

Talk to a few engine builders like KATECH and see if they really like PP springs which are made by associated spring...The PP stuff is OKAY but its not even close to a PAC or PSI beehive spring in terms of stability..

If I were to run a Dual it would be the Pac rated to .700 lift...

I wonder if this beehive spring was "harmonically challenged" causing it to break and phuch up an almost new engine..(less than 5,000 miles) whaddaya think...






I am not sure what kind of harmonics my dual springs have had over the last 3 decades...but they never have caused a droped valve or ruined an engine...they may not be harmonically perfect but they seem to be doing what they were designed for ... think I'll keep using duals ..

Any spring can break,doesnt mean that the style of spring is bad?
