I wondered if if the Moroso 8 quart pan would fit, cause it didn't have the two dimples in the pan like the factor had and the sqaure wasn't exactly the same either.
The factory pan had an angle on the passanger front side corner of the drop/center section that the Moroso doesn't. It fit, but I had to jack the motor a little higher that the factory had it cause of my fender well headers. So what I'm saying here is the dimples for the drag length werent nessasry, cause I'm higher.
I have two of the factory(well I say factory, they both have the dimples that most other car pans don't have) 273 pans for early A's. If you're able to do a mock up then I would try that.
My Moroso pan just barely fits. It was so tight that I couldn't put the motor in with the bell housing or with the pressure plate on. What a deal.
