Speedway Tech Talk - LS Oil Pans
One of the top things to consider when swapping an LS motor is the oil pan. The LS family has many different pans and they come in all sorts of different sizes based on the cars or trucks they were meant for. The trucks were larger as they offered higher oil capacity and the cars were smaller for fitment in GM’s sports cars.
For many of us, the LS truck motor was the best bang for the buck. Unfortunately, that motor came with a very deep oil pan that measured over 8” tall. For most LS swaps the truck pan will be too tall and once mounted in the car will be way too close to the ground. Of course being too close to the ground, means you will have to dance your ride around speed bumps and even those less then pristine streets that look like the Oregon trail.
Holley offers an aluminum pan item 4253021 that closely resembles the Fbody pan. The Camaro “F-Body” pan is probably one of the most popular style pans used in LS swaps. This pan measures roughly 5 5/8 tall at the sump. That makes this pan over 2 inches shorter than a truck pan and in most cases be protected by your engines cross member. The front of the pan measures approx. 2.25” tall and 14” from the front to the sump. This pan comes, with the hardware, and the pickup.
Here at Speedway Motors, we offer our own steel pan and it comes in Zinc 9101744, Black 9101742 or Chrome 9101743. This pan holds 7 quarts, which holds more than the 5 quart Fbody pan. The sump measures almost 6” deep and 11.75” from the front to the sump. This pan is slightly shorter at the front, which is great if you have a cross member that would need to be ground down for an Fbody pan. This pan has two AN10 fittings that provide oil to a remote mounted oil filter. This pan doesn’t allow you to screw a filter onto it like a factory GM pan, so a remote oil filter like item 7201056 will need to be purchased separately. You will want to mount this in an accessible area for when you need to change the oil. What’s great about this adapter is that it accepts an AC Delco PF1218 filter; item 91015175. The last thing to complete this part of your project is to purchase the oil pickup; item 9101745. Make sure you generously apply motor oil to the oil ring when installing it, as you don’t want to rip it.
