SKU: R1390 Chevy LS Series Motor Mounts
These LS and Late Model GM Motor Mounts are a great start for your custom build. We use the 5 bolt holes for the aluminum blocks. The iron blocks use 4 bolt holes so the 5th hole can be cut off. The tube capture location is not set in stone so you can move it around before you weld it to the plate. We do that because with all the LS engines going into all the different chassis and all headers will have their own clearance issues. These can each be custom fit to work best for your application.
