Will a 6 qt be enough?

Engine had the stock 340 windage tray in it when i spun the rod bearing. Should this be modified or replaced with a better designed aftermarket one. Local machine shop told me to throw it away. I dont think ill go that far. Thanks for any input. I realy dont want to do this engine a 3rd time. It probably would be fine if i kept it 6500rpms or less.

If you go with a real deep pan, like the 8 qt. that gets the oil away from the crank the windage problem pretty much goes away. I'm not positive but I think it was one of our members (OU812) that's a highly regarded engine builder did some dyno testing and found with a deep pan a windage tray is no longer beneficial. You might try a search for him and send him a PM and see what he thinks. Or if you prefer to run a tray you can do like 64 said and open the slots to help it drain back quicker.
