OK, I've been visiting this forum for a while now and enjoy how everyone offers up good advice when someone has a question. I'm running a 1969 Cougar 428SCJ (3:90 rear end, build Feb '69) with close ratio 4 speed (no's match). I just picked it up and thought I'd pull the pan to take a look at the bottom end.
Here's my question. The engine is still in the car. I plan to inspect the mains and rods bearings and would like to know if there are specific bearings I should look at? Should I not look at #5 (rear) so I don't have to replace seals? What about #3 thrust? Should I support the crank with a jack to prevent sag and false readings on the plastigage? Can I "over lift" the crank into the upper (block half) bearing and also create false readings? What about a tool to help remove the upper bearing? I've heard of a tool to insert into the crank oil gallery to "rotate" the upper bearing out and in. Where could I get one or has anyone fabricated a mock-up?
While I've got my hands in the bottom of the engine can anyone give any advice on what to look for in the bottom end of the cylinders? From my crude measurements it appears this block has had a 0.040 overbore. I can still see some hone marks. Cylinder #6 has a sleeve (yikes!):eek2:
