Car starts shaking badly and will not go any faster nor will it rev any higher.
Any idea what I should look at first? It is a fairly stock 396 with a TH400.
Thanks.

Need more info.
Has the engine been run at all in the past 3 years?
Did you flush out the gas tank and change the fuel filter?
Is it points or electronic ignition? If points, have they been replaced? How old are the plug wires?
Did you check for a vacuum leak?
Is it rpm limited or mph limited - - does it hit the wall at 2200 in each gear or just at 50 mph?
