These Motor Mounts allow you to bolt up an LS engine to the factory motor mount hole locations (for engine crossmember clearance against the oil pan, we recommend also using our H.D. Replacement Engine Crossmember!). They position the engine at nearly the same centerline as the factory small/big block so your existing radiator shroud should be able to be re-used. They also position the rear of the engine in the same location as your original small/big block - so if you are adapting to your original transmission, you should not have to modify the transmission crossmember or your driveshaft lengths. These use a H.D. polyurethane style bushing with a large 9/16" bolt (included)!
NOTE 1 - With these mounts and factory exhaust manifolds, you will need to notch the frame rails for exhaust flange clearance.
NOTE 2 - There is NOT enough clearance for the low-mount AC compressor! The compressor will need to be relocated if you are planning on keeping it - there are a number of different brackets available to move these compressors up higher if need be.
NOTE 3 - These are motor mounts only, not a complete kit by any means. You will need to research your swap completely before purchasing these.
