Which canton pan is it? The part number will be scratched onto the side of the pan. 15-820 or something like that, depending on which one. The canton pans are either the same or shorter than the Aviaids of which I think the Armando is a copy. I guess you have both right there to measure, but if you look at the specs online, it sounds like it tells a slightly different story.
If you have the canton road race pan on the engine already that Keith has installed and tested and it is leak-free, I wouldn't touch it. Leaking
oil pans are a PITA. Ask me how I know.
On the other hand, if you are going to change it at some point, do it now. One of the nice things about the Canton pan is you can remove it with the engine in the car. If the Armando is a copy of the Aviaid, then you have to pull the engine or jack it up quite a bit to get it off. If you have a stroked engine, it might mean that you can't get the Canton pan off either. Someone else will have to answer that as I have a standard stroke and still need to bump the crank around until the rods are out of the way at the rear of the pan.
Anyway, my $.02.
