I've rebuilt many SBC engines over the years and Never ran across this ; the cam will not come out of the block no more than 1 inch .
I think one of the rear cam bearings has spun . If so how can the now be removed?

Book said to remove the distributor, but the engine doesn't have one. Took me a while to realise the plug covering the dizzy mount also had the upper shaft for the oil pump. Cussed GM engineers for a while before I figured it out.
Current fleet (subject to change w/o notice) \'49 GMC 3/4-Ton , 60 Austin Healey Frog-eye Sprite (some assembly required), 2011 Dodge Avenger, 2015 Jeep Cherokee. No, they don't all run. My other ride is a (B737)no, (B767)no, A320.... Update... was Embraer E190, now Boeing B787. Knowledge is a wonderful thing, but ignorance means you don't know you can't do something.
