mjhcobra,
Dunno about the 428. On the 460, the Canton pan, even with the baffles, spring-loaded trap doors and scrapers that are built into it, it didn't work. On the track the
oil pressure went to zero in turns requiring me to ultimately install an Accusump in order to prevent expensive failures due to no
oil pressure.
I asked Canton at PRI whether they had any data or testing to support their claims that their pan is a "road race" pan as they advertise it. They said they had no test results or data to support their claim...
Don't know about the 428 pan. I'd be very very careful if you do a track day. Keep an eye on the
oil pressure in the turns. Mine would sometimes fluctuate the oil pressure if I did the zig-zag "tire warming" maneuver you see on NASCAR tracks, even if I did it on the street at relatively low speed.
Also be sure to measure and verify the vertical distance between the bottom of the pan and the oil pickup which on my engine is 3/8". Try not to deviate too far from that spec, and don't forget to include the thickness of the pan gasket.
