I have the Mckinney pan but with external pickup. Its very nice quality except they didn't deck the flange after they welded it. I had like a 1/4 gap which probably would be fine with a lot of "the right stuff" but i had it milled down flat anyway. I would highly recommend it. if your tracking a lot i would look into an accusump and i would also put an alarm on your oil pressure gauge. Not a lot you can do without opening the motor up. also probably put an extra quart in at the track.
