quote:What are your cam specs? Be sure to check your Scorpion roller rockers for clearance to the pushrod. Doug Braun on the DT Mail List had an issue with contact between the pushrod and rocker body (links below) and I had the same issue with my new engine. Given that you're using a Windsor, it may not be an issue. I believe the angles are a bit more extreme on the Cleveland, but my Scorpion Race Series roller rockers were spec'd to be capable of .950" of lift, and my cam is only .588" at max lift.
Just a follow-up on my own saga with the Scorpion roller rockers making contact with the pushrods. My rocker arms are silver, like yours, instead of anodized blue like all the Scorpion rockers seen on their website. According to the tech I've been dealing with, the silver rocker arms are an older version (possibly sitting on the shelf for a long time). The new ones are anodized blue and "have more clearance" on the rocker body to avoid contact with the pushrod. Be sure your engine builder checked the clearances there.
