I have a clacking in the left bank. Sounds like a rocker out of adj.

NOW, its and Eldelbrock Performer head with aluminium roller rockers, I do not know what brand or ratio, how would i find out what to set them to ??

 

Without knowing the cam make it will be tough , factory cams were .010 in & .020 ex
Lunati uses .016 in & ex , Mopar purple shaft cams are .28 in & .032 ex , comp is different again setting somewhere around .025 si a good start , if it still makes noise tighten them up more . if it is very lose check for a worn cam lobe .

Well if you think "most of the rest" are close measure them and see what they are.

Make sure you have the cam on the backside to measure. I use the "EOIC" method which means you bump (or wrench) the engine until

The EXHAUST just starts to OPEN you adjust that intake.

The INTAKE opens and is nearly CLOSED you adjust the exhaust for that cylinder.

There's a chart if you care to mark your balancer every 90*:

 

Is it a solid or a hyd cam ? Hyd would be .020 preload

 

Great info, Ive got a copy of the title and made a cal to the 2nd owner back, the one who built it, we shall see. I'll pull the covers this weekend and see what i have.

Thanks Guys.
