STL Mark,
Oh oh...
I have the Canton 460 "Road Race" pan also. In a word, it doesn't work. I know one other Cobra owner who used the same pan on a 460 and had the same exact problems.
The pan is likely OK for gentle street driving. If you corner spiritedly, even on the street, it stinks - the
oil pressure drops to zero or thereabouts. I discovered this first at a small track and then at Sebring - on right turns more often it would lose pressure. Nothing helped. I took the pan off multiple times, checked the operation of the trap doors, checked and re-checked the pickup-to-pan clearance and everything else I and Canton could think of.
Bottom line: the Canton "Road Race" pan for the 460 does not work. Possibly another brand, say Aviaid, Armando or other brands may work, but this one does not. I wish I'd tried one of them instead.
Solution? Accusump. Guess who makes it? Right, Canton. Wonder why?
Anyway that's the only solution for track use I know of so far. It's also great for pre-oiling if the car sits for a month or so between starts as happens occasionally with mine. I'm still watching the Kaase thread but with less optimism as time goes by since I don't have another 6" of ground clearance to work with.
Let us know if there re other possibilities!
Tom
