Rob;
The Canton pan is a very good pan. I went with Armando's pan because I have 4-bolt mains and Canton wanted $500+ and 5-6 months (special order) for their -580SV and Armando got it to me in less than a month for a little more than $400. I'm having pickup tube fitment problems, but that has more to do with the
oil pump than the pan.
