My car is shaking like a back massager at idle. Its kinda strange because it purrs like a kitten once you get at about 1000rpm. these are the specs on the motor.

intake, and exhaust general stuff.
no hole in the throttle body.
TR224/224 114LSA
forged bottom end that has 10.6 to 1 compression
TR55's at a .60" gap with MSD wires
all emmison stuff is gone.

Anyone got an idea of what the problem might be?

can anyone think of a single problem? Is the gap on the plugs too high? is the emmision stuff causing this? Or is it the motormounts?

mine I found out is the motor mounts. But I have no codes. Mine only acts like a bad idle.

You deleted all the codes for the emmision stuff right? That might have something to do with it.

I would check the plugs, wires, fuel filter, oil filter, and your gasoline.

When the car was tuned, did you get each cylinder checked for everything?

what tuning was done?

The plug gap seems a bit big given you have raised the compression.

You might turn the idle set screw a 1/2 turn to open the blade a bit more if your IAC count is high.
