So I'm buildin a roller 302 for a 89 f150, my roller rockers finally came in and they are pedestal mount arms but they have an adjustable pushrod cup on them. My question is what's the problem way to set these roller rockers? Iv never installed a set like these. Thanks!

 

Proper way to set them* sorry!

 

Are these from Comp Cams? They should come with instructions on how to set them. They should go something like:

To start, set the cup adjusters to their upper limit (maximum lash).

Hand-turn the engine so the valve you want to adjust for is closed.

Turn down the cup to contact the pushrod enough so that the rocker stops rocking. This is zero lash.

Then turn the adjuster down another 1/2 turn.

Tighten the lock nut, keeping the allen key on the adjuster if necessary to hold its position as you're tightening the nut.

 

Yea there comp rockers but I got them new off eBay and they didn't come with instructions! Thanks for the info though!

 

You might also check Comp Cams's web site to see if they have the directions online, or failing that give them a call on Monday to see if they can send them to you.

Edit: just went to their site and they have instructions online. Go to http://www.compcams.com/Instructions/
