Ok I just re ringed and bearinged the shortblock in my iron 6.0 and added arp rod bolts. I put some 241 heads on it and the magic stick3. I used the standard length push rods and the PAC beehive springs that are good to .650 lift. Well we got it started finally and the a loud *** sqeakimgnoise start and began to get worse and louder til when I let off the throttle it just died. Theengine ran for maybe 2-3 minutes and would hold 45psi oil pressure at 1300rpm or so. We pulled the valve cover off and notice some of the rockers looked dry. But not all. I'm running just regular oreilly oil with a half quart of Lucas for breakin. Any ideas what's going on the noise seems to be from up top. Any help would be great. Thanks
