[HWYSTR455]

I know with 455s, or long stroke engines, there's a chance of sucking the stock pan dry, and the general fix is to run an qt extra. Windage is the factor, as well as slosh & slow drainback.

There are threads here about it, search it.

If you have a windage tray, it helps with windage, which is the only drawback when running 'too much oil'. Of course, you don't want to fill the engine up to the valve cover breathers, but that's a no-brainer.

Most racers etc will tell you windage can cost HP, general consensus is in the 5-10 HP range. If that's felt as a dramatic difference, you're probably only making 100hp total.

I run 7+1 in my Canton pans, the docs are not right in saying 6+1, the pan is listed as a 7qt, not a 6qt. So you be the judge.
