i got a set of used manleys for a baby cam im about to install but seen they had two install heights, 1.75" and 1.8". would anyone know the right height for a set of manley duals? thanks

 

Which Manley springs? Is it their kit? If not, what retainer are you running? What cam specs are going with it?

 

im assuming its a kit was pulled off ls1 heads. It looks to be a dual spring and steel retainers. cam is just around 218/228 554 570. thanks bud i hope to get started this weekend when i rent a damper puller

 

Manley is liking providing two seat values at two installation heights. The actual installed height is determined by the seat value required by the cam. I would shoot for 135# on the seat and figure out what installed height is required. Do you have a shim kit to adjust the seat value (installed height)?

 

no i dont have a shim kit, where can i get one? im gonna run a 10-12 lbs also thus the reason for the spring change but found this cam for pretty cheap.. thanks for your help

 

Not sure what your seat value should be for a boosted application. I would contact Manley to get a value but you probably need more seat force then 135#. The shims are available from Comp. Manley may also have them.

 

10-12lbs I would shoot for around 140-150 closed and 400 open.
