I got the shakes

[nhl77]

And not because I have no heat (which I don't) but the motor shakes. I built a new motor last spring with an edelbrock performer package and MSD ignition. The problem is the motor shakes the whole car at idle. I'm pretty sure its not the motor mounts but I am going to check them as soon as its not butt Great Googley MoogleyGreat Googley MoogleyGreat Googley MoogleyGreat Googley MoogleyGreat Googley Moogley cold out. Any other things I should look at?? possibly vacuum? Thanks.

Did you tune up the motor after install? Timing set correctly, spark plug wires in the correct sequence at the dizzy and plug end? My first guess would be a crossed plug wire.

How long has it been doing it?? If it recently started then I would look at your vacuum lines or EGR after you check the ignition.
