Well, I finally received my new pan today. I eagerly flipped the motor over and set it over the stud girdle. It doesn't fit!
And this is a non-returnable part.
So what are my options for a pan and this stud girdle? The Canton is about 1/2" shy if fitting all the way around.
351W stroked to 393 and had a Blue Thunder stud girdle.
Pan is a Canton 15-680 front sump.
