MOROSO LS Engine Swap Considerations

First you figure out how you are going to mount your LS engine, then you ripped out your old engine, wiring, and the other ancillary items so that your engine bay is ready for a new or  new-to-you-LS engine.

You already purchased your Moroso LS Series motor mount adapter plates (P/N 62555) right?

These plates are a  simple and efficient way to adapt motor mounts to fit LS Series engines. They are made in USA  of high-quality material (6061-T6 aluminum) right here in the USA and include the necessary hardware.  The black anodized finish resists corresion.They work with GM factory 3-bolt mounts, Moroso solid motor mounts (p/n 52500, 52510, 52515 and 62530) and most aftermarket polyurethane mounts.

They locate the bellhousing mounting flange approximately 1″ further forward than the standard small block location.

And you’re future-proofing the oil system too right?
Because if you are driving on the road course, autocross or drag strip occasionally, you want to make sure that you have  protected your new engine from oil starvation or from putting extra heat into the oil from an unbaffled OEM oil pan, an aftermarket piece that’s designed to address these issues provides added protection. Even if your project isn’t a full-on competition build, there are still a number of reasons, you’d want to consider opting for an aftermarket oil pan rather than sticking with the OEM piece.

One, the weight savings can be even greater when compared to the typical pans used on street cars. Moroso has various oil pans for Chevrolet LS and Dart LS. ie. p/n  20145 is a Street/Strip oil pan for LS swaps where a rear sump is required.

Another reason, chassis restrictions where Crossmembers can  interfere with an OEM pan in certain situations, so an oil pan with a shorter front to back sump may be needed to  to clear these crossmembers.

And some swaps can require a front sump oil pan instead of a rear sump oil pan.

Just make sure that you consider how you are going to drive your vehicle. You can use an oil pan designed for road racing for drag race oil but not the reversal because of the lack of a reserve of oil during cornering.  Thor Schroeder at  Moroso Performance explained in Enginelab’s article on Choosing the Right LS Oil Pan:

“Drag race oil pans typical have an oil collection sump that doesn’t T-out on the sides and a baffle towards the front of the oil pan to feed the oil pump pick up area during acceleration. While Road race oil pans will have baffling that keeps oil contained in the oil pick up during cornering. For instance, if you make a left turn, a trap door on the right side of the oil pan will swing open and let a reserve of oil go to the oil pump pick up area,” he continued. “The trap door on the opposite side of the oil pan will swing shut so that oil can’t escape from the oil pump pick-up area. If you make a right turn, a trap door on the left side of the oil pan will swing open and let a reserve of oil go to the oil pump pick-up area and the trap door on the opposite side of the oil pan will swing shut so that oil can’t escape from the oil pump pick-up area.”
