i just remember reading somewhere that if you got a double spring package it had double retainers and all the business some where said you needed different heads, but yea if you want a tried and true spring comp918's can be sworn by especially if the no name manleys arent even rated for that lift,

 

Hmmmmm

 

PM 01thunder. he has a tr224 (way high ramp rate) and has been running the same springs for over 30,000 miles. The 918s can take a beating!

 

Cool, I guess I will go with the 918s then. I wasn't sure if they would hold up but I have heard a lot of good things about them before.

 

The thing about a performance spring is that they are stronger yet more brittle. Once must have the engine warm in order to be able to beat on it. You cant just fire up the truck and hammer the hell out of it without running the risk of breaking a spring. The stockers are able to take a beating from the word go but the you need to let your engine hit running temperature before you lay into it.

 

i too have heard that beau but some members on here say they dog their 918's from ignition and havent had any problems yet but their ramp rate probably isnt to bad but yea to pla it safe, and keep your pocket from empty, let it warm up a bit but you figure you have to drive somewhere before you race so it should all work out, man people die by their 918's

 

I have Manley dual springs good for .650 lift and didn't do anything to the heads. I also have Ti retainers I just didn't want to have to change again. Lets face it the C2 cam isn't very big or aggressive.


Oh and Manley products are about as far from being "No Name" as Comp or Crane

 

the C2 cam isnt huge or aggressive you are right but for those of us who still want to drive our trucks without NEEDING to spin up to 4000rpm to start moving its a good choice, a lot of people here say a 224/224 is a little big for DD 5.3's and recommend 216/220 or 210/216 or something, you wont really find many people here running 23x/23x cams with 6xx lift. but how much did your manley dual springs run you? seems like a good option, and what cam are you running with what set up? im not trying to be a smart *** im just wondering what you have

 

I have a C2 cam in a 5.3 with 10.5:1 comp, p&p heads, 2" intake valves, and full bolt ons. I have a tt3000, built trans, and 4.10 gears with a true trac. Your right you don't have to rev it to 4000 to get it to move and it pulls above 6400. I tow a 5000Lb trailer a few times a month with no low end problems.

I just think the cam "trend" is getting bigger more aggresive. High duration "220+" OR high lift ".600+" who wants to change springs twice? It takes twice as long as changing a cam, do it once.

I payed $200 for my springs and Ti-retainers with only a few thousand miles on them and they came with a free set of LS1 heads

I guess what I'm getting at is nobody is ever happy with their first cam so get the valve train that will support the second. I had a TR224 and 918's with stock retainers.

Have you guys seen this thread?

so how happy are you with the C2 in yoru truck, you cant expect to comment on it without goiving a review can you? are you satisfied? is it better than your tr224? and have you ever done any dyno pulls on it or run some et's? good choice for a DD cam or would you go bigger or different specs?
