440 rocker lift ratio

[Aussie-cuda]

Hi I need to replace my rockers and I don't know the lift ratio due to my rockers been very worn!! I have a mopar purple cam not sure the specs! Does any 1 know the stock lift ratio?? Thanx

The stock ratio is 1.5 to1 .Why would you replace the rockers if you don't know the cam specs and the lifters are worn ?

Thanx, the rockers are warn and making a chattering noise at about 40-50mph.the motor is suppose to be fresh but they must have put the old rockers on otherwise the engine runs really well.so I'll buy some stock ratio rollers to replace them.

Sorry my first post was a mistake I ment rockers were worn and loose on the shaft!!

I would recommend pulling the intake manifold and valley cover to inspaect the cam lobes and pull the lifters to check for wear. If the parts are good remember to replace them in the same place you remove them from. Engine noise on a "fresh" motor is sometimes a sign that you need to verify what that means.

Yep I got a new manifold to install anyway so I'll check cam and litters while I'm there thanx mate

Hey do you know any1 who has a second hand set rocker arms in good condition so I can use them untill I work the motor?? Thanx

Yeah. How many sets do you want? But I think that might not be the problem. Even brand new ones will slop around on the shafts and look like they are worn out.

you have to check the pads that ride on the valve tips if they have wear in them they are bad
