Mike:
I've got a Coast High 351W stroked to 408 with a Canton pan. Same problem, leaks at the back, and now the front. Pan is not square with the fly wheel cover and the rib radius on the pan runs diagonally(sp) across the seal in the main cap, and extrudes one side of the seal out of the main cap groove. Have had the pan off 5 times, tried everything, even the Summit one piece, no luck. However, Fel Pro has an pan gasket #1827 that is metal. But when I got it, the second hole on the right side rail did not match up, so I went with Fel Pro FP 1810. Front's still leaking, but it may be something else, back still extrudes the seal out, but it is not leaking yet, but I give it a couple of days. I am looking for a different pan also, the cast aluminum Cobra pan, but they don't make them fot the 351W anymore, so I am still marking my spot. A real pisser!!!
