Motor Shakes A Lot Without Being On
I installed the motor after doing a rebuild and I physically shake the motor by the manifold and it just jiggles back in forth. I just started the motor today and my idle is at 1,400 RPM so it doesn't shake that much, I don't know if it was set that high by previous owner so i wouldn't notice it. Mount brackets and mounts are tighten up. I noticed when it would decelerate it would shake.
Could it be worn mounts? Should I switch to polyurethane mounts?

He is referring to where the trans mounts to the PPF. If the trans bolted in securely and assuming the motor is bolted to the transmission properly you really shouldnt be able to move the engine much. If your mounts are completely shot I think it would be possible to move the engine side to side but not easily and not a whole lot.

sounds like something else to me, like a loose PPF mount bolts or driveshaft bolts.
i once had a customer come in and the car had a vibration like you describe, while on the test drive to try and figure out what it was the driveshaft nuts all came out and the shaft slammed into the muffler. so double check that anything you removed gets put back in and tightened, his obviously only made it to the finger tight- if that, stage.
i sure was glad it happened while going 20, since he actually wanted me to road tune the car....

Well it use too be fine, I bought the car like 50 miles away ran fine, no problem but a couple of days later I found a little leak in the coolant seals so I sent the motor to get rebuilt. I installed it a week ago and notice that when I shake it with some force it would jiggle. But I will look at the transmission brace and driveshaft. Thanks

it will move to an extent, every engine has some give which is normal. problem i have is the FD mounts have straps that will prevent it from lifting up very much even with completely torn mounts. unless the mount was installed without the strap and the mount happened to completely rip through, then i am inclined to agree.
