Seems like I can't just use anything as it comes from the factory. Since a 200 I-6 makes a whole whopping 80 HP, and about the same amount of torque, I'm concerned that the stock, gay-La-Fair motor mounts might not be up to the task. I could use them, and then add a chain to limit the rotational twist that'll come when I stand on it, but chains are gay. I have had project cars before that have had either a front plate, of solid mounts holding the engine in before, and I don't recall whether or not the engine vibration was that noticeable, but then again, I don't think I cared at the time. This time I might not care either ( at least initially) Given that an I-6 is characteristically smoother than a V8 It might not be that bad. Thoughts?
