I have a '55 chevy 3100 with an LS1, and can not determine the proper amount of oil it requires. (I know it's 5.5-6.0qrts for an LS1 with f-body oil pan, but please read on)

Here are the facts: LS1 from an 02 camaro; as some of you may, or may not know, some of the 02 camaro's got the LS6 block...my engine falls into this category. It has a lokar aftermarket dipstick for an LS1 and a stock f-body oil pan. I pulled the dipstick (tube and all) and measured from end of the tube to the low and full mark- same as another LS1 Lokar dipstick that I was able to get my hands on.

Now for the delimma: It has 6 quarts and is only at the "fill/low" mark on the dipstick, suggesting it is still a quart low. I don't see how it could take 7 quarts to fill! Is it possible the LS6 block requires a different dipstick than the standard LS1? Could it be an internal engine issue...poor drain back or something else?

I'm really pulling my hair out over this! Any ideas or suggestions would be greatly appreciated!
