On my build I have mounted my engine using urethane bushes without considering how much vibration it may put through the car.
I was chatting to a friend who had done this once and said it was a bit harsh.
Now would be the time for me to change it rather than later.
I don't mind a bit of vibration, but do not want it unbearable to the point where I won't want to drive it.

Any thoughts?

cant see there being a huge issue, chevy engines are solid mounted remember and they probably vibrate as much as anything
not from the factory on road vehicles.
having said that i've had a few solid mounted v8's and they're fine for road use. maybe your mate's talking about 4 pot's as they can be buzzy.

Replaced both stock engine mounts on my Vette with Urethane mounts as stock ones were always spitting apart. With the manual gearbox it actually improved the gearshifts with the stiffer set up. Solid mounts on a road vehicle needs some thought re. additional stress to chassis and risk of stress cracks.

think a lot of race cars used a solid mounted engine as part of the chassis
think its more the road vibrations of normal road use going through the engine causes more of a prob

could be wrong on all that though :)

Blue Gene Pop 1 used urathene engine and trans mounts and despite being a 9 sec race car, it was street legal and covered 1000's of road miles. Transmitted engine vibration was never a problem, which is more than I can say for the transmitted banging and crashing of completely rose jointed suspension and the "comfort" of race seats!
