J,

First page of the instructions had this little clip. Which means they are only designed to fit the LS3 tube unfortunately.

The Holley® LS Swap oil pans are designed to work with an LS3 dipstick and tube (if desired). Below are the part numbers:

· LS Dipstick – GM P/N 12634547

· LS tube – GM P/N 12625031

Thanks, Holley

Thanks Holley,

I am using the pan on an L76. Can I use my standard dipstick, or do I need to go to an LS3 dipstick?

Best Regards, J

Thank you for contacting Holley Performance Products.
The pan is designed to hold the 5.5 Qts.  The over all capacity with a filter is 6 Qts.  The filter hold oil as well creating the half qt extra.

Your question was:
The product technical information makes the comment that the sump oil capacity = 5.5 Quarts Total Oil Capacity with stock oil filter. 6 Quarts Requires use of LS3 dipstick (GM P/N 12634547) and tube (GM P/N 12625031). My question is, what drives the decision to go to 6 quarts over 5.5 quarts?
