do i HAVE to use the crane valve springs with my crane #14 cams, or can i use my stock springs???
i was told that i could use the stock springs, but i wanna make sure before i do it since i was also told that the crane springs would need to be adjusted for the right height and load and am now running out of cash for the time being due to my block problem[:@]

so anyways, if i can use the stock springs them im just gonna throw the cams in another head i have sitting around, or if i can just install the crane springs myself, then i will put them in anyways....but only if i can just simply swap them out with my stock springs

 

You NEED to use a better spring than the stockers for anything over the cran #10.

The reason is the stock springs just cant handle the more drastic cams. You might also need the titanium valve spring retainers. I am pretty sure on that because the spring retainers are not rated for much higher than the #12 cam.

Just my .02

 

well that just figures

do i have to do anything else to the head, or can i just swap out the springs and/or retainers????
do the springs need to be preloaded???

 

Yes you need to upgrade the valve springs and retainers.

Springs don't need to be preloaded.

 

I got the Mopar performance valve springs in mine, they are around $180 and they work great...as far as i know anyways...

 

Crane valve springs for a DOHC are only $100 and are $140 for the SOHC from Modern Performance.

 

i alredy have the crane valve springs, just wanted to know if they were deffinately needed and if i would be able to just put them in myself......but i guess i need to order the retainers now then too[&:]

i was just looking at the prices on mpx....i sure am glad i dont have a sohcespecially for the retainers

now i just have to find out if they will sell the retainers only

 

wow....that sucks....I really wish i would have got mine from there...but i didnt know about modern performance back then

 

There was a guy on the dot org, that was testing his stock springs on a 14. I dont know what has happend since then.

 

I wouldn't put the cam 14 in without upgraded retainers.
