Is the engine in good condition?....fairly stock or?
If it is, perhaps changing from that well used Holley over to a Quadrajet might be a good move.
That manifold is typical of the late 70's and 80's intake manifolds with all the smog ports, etc that came on them.
If you are looking at getting a little more performance perhaps upgrade to a Edelbrock Performer (dual plane- NOT single) manifold.
Are you pretty mechanically handy? I would start by removing that carb and giving it a very serious (carb cleaner) clean-out and compressed air blow out to get things rolling.
The other issue, as mentioned by the guys, is to make sure your timing is set properly. Do you have a light and the capability to check this?
My two bits.
