How much intial timing are you running??  How about total?? 
 
Is it a Holley??  Check the float level first.  Then also see if you have Vacumn and how much. 
 
Which power valve is in it?? 
 
Bump the primary jets two numbers and see if it helps. 
 
What do the plugs look like?? 
 
There is a good start for you.
