To go with my Harold cam, he recommended the Lunati 73100 spring. It's a dual spring with damper. They showed up in the mail today, and I can't for the life of me figure out how the inner spring comes out so that I can put the outers on to breakin the cam.

They are a tight fit and don't budge at all.

Is this a spring that I should just put on and use lots of lube for the breakin?!

Anyone?

are you sure its not just the spring and dampner?

What are the spring specs, the cam specs, and the rocker arms?

tw, (Name ??)
They WILL come apart ... just have to work at it. I have had to use our spring checker to get them started. Sometimes its not easy, but they will come apart.

Cam is a TF80/TF72-112 239/247 @.050 .544/.566 lift (1.6ratio) 112lsa. Solid tappet. Springs are Lun73100- 1.450OD .730ID, 1.850=125, 1.250=325, bind=1.110, lift=.680, rate 333


I was able to pop the spring out with a screw driver and work it out. Thanks guys!

just wanted to make sure I wasn't going to fubar something.
