Considering changing the engine mounts from rubber to urethane. Anyone have any experience with such a swap? Wondering how much additional vibrations I will feel and what the throttle response will be like.
I have no experience but can give an opinion !! got a set for the 58 I'm building but haven't installed them yet. Anyways I think they are more for strength and lasting longer than rubber. The rubber would absorb more shock and flex abit compared to the rock hard urethane. But the engines of today run smooth like a electric motor and don't shake like the good old high compression carb fed torguers. So, I don't think you will notice any difference as far as feel , but they will last longer and should not break lose in extreme torgue situations. They also come in colors which look kool.
