Reply to "oil capacity"

David,

the larger width & length of the sump of the high capacity oil pan will require more oil to keep the oil pump suction bathed in oil at a certain level.

While you have the oem pan off & before you install the new pan, you'll need to take some measurements, add measured amounts of fluid to the pans & get an idea what the minimum & maximum amount of oil your pan requires. Keep in mind there is 1 quart in the filter & at least 2 quarts circulating in the engine, at high rpm there can be 3 quarts circulating in the engine. If your larger pan requires 3 quarts to keep the oil pump suction bathed in oil, then at high rpm you'll need 7 quarts, minimum. 3 + 3 + 1 = 7

Having said that, the oil level in the high capacity pan will not vary as much with the loss or addition of 1 qt of oil as it will in the oem pan. So the large sump pan may allow you to add 2 extra quarts, where with the oem pan you can only get away with adding 1 extra qt.

If you think of it from that point of view, the ability to "stuff" more oil in the pan, you may be able to stretch the miles between oil "fill ups".

I say this for the benefit of others reading this post, if you purchase a stroker kit in which the piston wrist pins intersect the oil ring grooves of the pistons, your engine WILL burn oil. High volume oil pumps will exacerbate this problem.
