About 3-4 weeks most of the time. Think about bushed rather than bearings......just my two cents. They say ten weeks for steel rockers, which in my opinion are 100% better, but it has never taken ten weeks to get the steel. You would want the 7030 set. There are options, and depending on what manifold is used, I get various offsets to fit the pushrod tubes better. I am a T&D distributor. I guess there are others. You can buy them directly from T&D, but usually a dealer with FE experience can help you, and give more info on the FE specifically, than the guys on the phone at T&D.
