Re: Rubber Rear Main Seal
I tried to look it up, but the service manual only gives the O.D. of the rear main bearing journal, which is 3.1239". It may be the same diameter where the seal rides.
Most Pontiac V-8's also used a rope rear main seal. I am rebuilding a Pontiac 326 for my cousin as we speak and can verify!. The 301 was a real oddball, most everything about it is different compared to older Pontiacs.
