Series I Rocker Arms - 1.72:1
 

Trying to locate a supplier for the above specialized rockers, maybe even the manufacturer which I believe resides in Australia. Can anyone help please...thanks

Thanks, I am aware of DrJay, really nice and knowledgeable gentlemen. However he wishes to get X number of orders together, then place a large order to Australia. I can't wait, unfortunately my timeframe is limited...

Naw. Doc can 1 off order :-). Just tell him you're too impatient to wait for the group buy.

Yella Terra is the company that makes them.....im sitting here thinking...there cant be that much of a advantage from the stock 1.6 to the YT 1.72's...

wouldnt a cam with the stock rockers be more of a gain

They are also full roller rockers. Stock are not.

Thanks, I figured as much; It works out to ~20% increase in lift, maybe 10-15HP. The scenario I am working on would lend itself to just adding the rockers on an existing powerplant that is already installed (cam removal impossible without dropping the front clip).
