I'm having a hell of time trying to install my new rope crankseal seal for my 1953 235 engine. I've taking the tranny out and loosen the crank bearing caps to give me more room. HOW MUCH CAN THE CRANK DROP WHEN LOOSEN? I got it to drop about 1/8" I've tried to pry it gently to bring it down some more but that all I got. Is that the most I can get? I just can't get the rope seal to insert in the groove of the upper bearing cap it's to tight and not enough clearance betweeen crank and cap.
