16Gomango, put me down for one of your magnetic pan plugs please.
BTW, I had a 6.1 stroker motor built probably 10 years ago by BES Racing. Beautiful engine and I had a beautiful aluminum sheet metal pan made for me by MOROSO. Metal art work it was. Anyway, BES put ARP studs in the bottom end for me and when I got the engine back and onto my stand, I tried to fit the custom pan on it. Moroso uses a real beefy CNC machined pan rail and it wouldn't clear the studs at the back. I forget exactly what part of the studs, likely the nut and washer. I ended up clearancing the thing with two nice, half round notches in the rail and all was well. Really thought it was just a problem with the rails used in the Moroso pan. Really surprised to hear a stock pan won't clear either. Good to know for future builds, if I ever do one again.
