Dipstick tube
Dipstick
o-ring that goes on the top of the dipstick
o-ring that goes on the bottom of the dipstick tube
Now both the dipstick and the tube may have the o-ring included; I don't know. If they do, I can send the extras back.
Wonder how much the Holley pan will be?
The Best V8 Stories One Small Block at Time
Does anyone know the dimensions of the GMPP "Muscle Car Pan"? How does it compare to the F-bod LS1 pan. It sells for much cheaper and I want to see if this is an option.
EDIT. Looks like that kit contains the LH8 pan but I am still unlcear on its dimensions when compared to the F-bod pan.
EDIT #2. Looks like it is 2.5" deeper than the f-bod pan. Lots of info in this thread!

Although Holley’s GM LS Retrofit Oil Pan uses a traditional rear sump design, it maintains the factory LS five-quart oil capacity (six-quarts with filter) and structural rigidity. The external sump depth measures 5.89” from the mounting flange, 7.65” from the bell housing flange, and has an external sump width of 9.75”.
I have both pans, but I was wanting to use the f-body pan because it seemed easier to modify. Now for the truck pan, I have no idea on what and where to cut. I actually have no idea on where to cut neither one of them. This is why I was needing help.
Here are some detailed pictures of the one I bought and my personal thoughts:
I have to say I am very impressed with both the design and quality of fabrication of this pan. I have seen aftermarket pans for small blocks that didn't come close to the level of detail built into this thing.
The pan is constructed of a stamped section that formes the one-piece flange and front section of the pan and a welded/fabricated sump area that includes kickouts for capacity and active baffling for oil control. The efforts toward keeping oil around the pickup were my primary reason for selecting this pan over some of the others available. Here are some detailed pictures of the sump area
You can see the pan uses hinges as doors to keep oil around the pickup during cornering, braking, and acceleration. The hing travel is limited to opening about 45 degrees, which shold prevent the doors from sticking open.
Another detail to admire is the stitch-welded backup flange that adds thickness/stiffness around the perimeter of the pan to help keep things sealed.
The pan also includes a nicely machined spin-on oil filter adapter.
These o-rings seal the supply & return between the adapter and the oil pan. I was very happy to see the o-ring glands include room for the o-rings to compress, a detail that some (bad) engineers overlook. This should result in a good seal as long as the bolts clamping the adapter do their job.
I haven't looked up this filter yet, but here's what you're supposed to use for this pan.
The pan also includes this fabricated pickup assembly. I suspect (but dont' know for sure) this started life as an OEM assembly and was simply modified to accept the pickup in a new location. My only complaint here is some surface rust around the MIG welds that could have been prevented by oiling it down before storage. We'll see how well it lines up when I install the pan. I do plan to check the distance between the pickup and bottom of the pan.
