Chevy LS Motor Mount

Team321 V8 Motor mounts Chevy LS V8
for Narrow Crown Vic Front Suspension Crossmembers
I borrowed an LS block and make a mock-up of the block to mount the oil pan, motor mounts and exhaust manifolds. This engine block mock-up allowed me to test fit the motor mounts. I am looking to purchase an aluminum LS block… does not have to be functional – just good enough for mock-up duty.
Here is a better detailed view of 3D CAD image showing the motor mount components. The associated hardware will be provided as well… but for the sake of showing how it all fits together, the hardware was hidden from the image.
The image below shows the contents of the Chevy LS motor mount components.

Team321’s goal is to provide a variety of motor mounts that can be interchanged and easily installed on the Narrow CV crossmember… including retrofitting all the crossmembers sold over the last couple of years.
Installing the motor mounts on new crossmembers is straightforward… installing motor mounts on older crossmembers requires one additional step… drilling two pairs of 3/8″ diameter holes in the crossmember plate.

Installing the motor mounts on older crossmembers is as easily as locating two holes on either side of the crossmember. Here is a picture representing the side plate of the Narrow Crown Vic Crossmember.

Position the Paper Template (provided with the motor mounts) on the steel frame and centerpunch the holes indicated by the red arrows.

Once these 3/8″ holes are drilled,  you have the locating points for the motor mounts. These 3/8″ holes can be drilled in either the forward plate or the rear plate – on both the drivers’s and passenger’s side. This allows for options in positioning the engine. The brackets that mount on the engine can also be mounted in either orientation. These combinations of mounting positions allow you to choose how far forward or rearward to mount your engine.
The photos in this install sequence show the 3/8″ holes drilled in the rear plates and the engine mount bracket positioned with the small gusset pointing downward..

If you purchased the crossmember prior to these holes being standard…I will mail you a drill template at the time of motor mount purchase to easily modify your crossmember to accommodate the motor mounts.

Generally, motor mounts consist of a bracket that mounts to the engine block, some type of bushing and plates permanently affixed to the crossmember or truck’s frame.

Team321 has test fit these engines with rear sump oil pans and factory exhaust with no crossmember interference…

The 3/8″ holes you drilled through the crossmember plates positively locate the motor mounts… insert the provided 3/8″ mounting hardware to locate the motor mount plate.

Once you have the driver’s and passenger’s side mounts properly positioned and you’re happy with the engine’s fore / aft position on the crossmember, weld the plate to the crossmember – as indicated by the green overlay… once welded the 3/8″ hardware can be removed and the holes plug welded.

Here is a pic of the mount including the triangular gusset on the Driver’s side.

here’s a pic showing driver’s side… the interface between the ORANGE colored plate and the crossmember. In some cases this ORANGE colored plate may need to be trimmed to fit… the plates provided are raw steel, I show colors during install sequence photos to more easily identify them.

The image below shows the passenger’s side… note the brackets and triangular gussets are smaller on the passenger’s side vs. the brackets used on the driver’s side… this is due to the offset of the engine toward the passenger’s side.
