Hardin/cp perf 14 qt pans IF you have room then run 12 if its taking too long to warm up oil. Cantons BOX offshore pan appears to be popular too, I bought the 10 quart ones with power pouches and they starved for oil on dyno, joe G/ mild thunder has had good luck with the plainer, boxed offshore version from them. I used kevko pans on 3 motors, they worked good, were reasonably priced BUT the bravo raw water pump was touching the pan and I had to modify the brackets, longer belts, not worth the trouble. They DID modify a couple for extra starter clearance as I also ran into issues with that but didnt realize the pump clearance issue until I went to dress them out and install them. The Jegs pan mentioned above, I could flex it with my thumbs fwiw, Smitty
