It definitely sounds like some basic tuning is on order to optimize the engine and the advice above is all good.

After that is taken care of I suspect the car will still be a bit of a dog for the very reasons that shine wrote

"......my guess is your power curve does not start until 3k + . high comp - big valves- big carb - daily driving it will be a dog most of the time and likely load up a lot ......."

Add to that that that it is a fairly heavy car and the standard rear gear for the car (with automatic) was/is a 2.56, it will be no ball of fire from a dead stop.

Personally I'd start saving for a deeper set of gears, possibly a looser convertor (depending on the cam) and an overdrive tranny if you plan of doing any highway driving.
