Default motor mounts

in my 80 we put the new intake and carb on and its running good but we have the hood off to fix the headlights and the motor seems to jump alot when you rev the motor and put it into reverse. We checked the motor mounts and they look fine. does anyone else notice this?

HOW DID YOU CHECK THEM. did you put car in gear and hold brake on while giving it gas to see if engine lifts?

I took a jack and lifted the motor up with a jack and it lifted the whole car up but when you brake torque it moves 5-7 inches up and to the right

it shouldnt move more than and inch or so. 5 to 7 ,its gotta be broke. to check it with a jack you have to put a 2 by 4 under the driver side of engine standing up on a floor jack. if its broke it will lift driver side of engine. you cant put it in the center of engine.

From what you describe. One of them is broke. Replace them ALL.
They are cheap. You'll be glad you did.

Agreed... replace the motor mounts. That was one of the first things I did with my car, and without that engine throwing its weight around in the engine compartment, the car handled better too in my opinion. I went with poly mounts, and my engine moves less than an inch... pretty much not at all.

you may want to check the transmission mount also if the motor was moving around a lot it may also need replacement.

I went with poly mounts. When the engine revs, the car shakes with the torque. Love it.

Be careful when you buy mounts i bought some jobber mounts from the local parts store, and the bolt holes were not slotted like the stock ones and they didnt line up. So i ended up putting in solid mounts, they bolted right in.
