Not sure if this has been posted yet or not, however, I found that I had a problem starting the car with the standard serpent box due to the width of the rubber pulley and the width of the chassis not allowing proper engagement.

Fix !!! kill two birds with one stone !!!!

The key number is .080 " take .080" off of the motor mounts and you not only lower your cg of the engine but it allows the starter box to contact the surface of the flywheel much more effeciently !!! Additionally it still allows for clearance between the chassis and the engine.

I am using a Novarossi S3 so the measurement may be slightly different depending on which engine you are using, However, it's an old trick to lower your engine and there is plenty of room.

I also use the serpent # 6361 rear belt, (wider) I have never had to replace one, and would assume I never will.
