Provide Needed Clearance for Your Big Block Chevy When Using G-Comp Suspension

Our popular G-Comp and G-Comp X Edition bolt-in front suspensions are designed to use the standard 3-bolt SBC/BBC motor mount. This means that once you have the front clip installed in your Camaro, Nova, or Chevy II platform you can run either a small block Chevy (or even an LS with our LS motor mount adapter plates or a big block Chevy. While the SBC is often the easier and less expensive route to take, we know that there are many diehard BBC fans out there.

However, with the BBC option there are often clearance issues with certain oil pans and our crossmember. While you can obviously modify or fabricate a custom oil pan, we also know that many are looking for a simple bolt-in solution to this issue when it pops up (and it may even happen with certain SBC deep oil pans as well). To that end, we have created these BBC motor mount risers for those that need extra clearance. Crafted from 1/2-inch thick A36 plate steel and clear zinc coated for corrosion protection, they mount directly to your SBC or BBC engine block, providing relocated mounting holes for stock or polyurethane SBC motor mounts or BBC motor mounts. We include robust 3/8-16 mounting hardware to attach the motor mount adapters to your engine block and your motor mounts of choice to the adapters as well.

Perfect Fit for Big Block Chevelle

I used the G-Comp Suspension Kit – Big Block Chevy Engine Mount Spacer Kit on my Chevelle with a big block, and it worked exactly as advertised. The spacers were well-machined, solid, and fit perfectly between the frame stands and mounts without any modification needed.

Would Recommend

Good design, well made, excellent hardware.

The inner tie rod ends were hitting the oil pan (SBC) of my 67 El Camino when the steering neared full lock position, denting the pan. I needed to raise the engine or modify the oil pan. Installing these spacers solved the oil pan problem, leaving only millimeters of clearance below the hood. I'm grateful these spacers are available. Just adding washers or a plate beneath the engine mounts would not work due to the misalignment created that way.

Used these with long mounts to solve oil pan clearance issues in a 1974 Nova we dropped a 396 into. The spacers with the long mounts lifted the motor right up saving us from having to do a lot of unnecessary fabricating and wasting time.
