Oil Pan

Time to swap the standard Holden VZ Commodore oil pan for the Holley LS conversion oil pan (Part No. 302-1) to suit B-bodies.

The 302-2 developed for A-body Chevs is not required (I hope!) as the Impala has the steering drag-link at the rear of the cross member and lower down, so there are no issues with the drag link fouling the sump.

Because the two lowest engine-to-transmission bolts picks-up the sump, the trans and engine need separating...






We lifted the 4L65E onto the workbench, ready for cleaning prior and hitting with a few coats of clear-coat.

With the sump off, we could have a look at the crank, underside of pistons and the base of the bores; looks pretty good...




Holley sump going on...




A very nice product from Holley; good bit 'o kit.

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.
Sincerely,

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?
