Is that what 330 HP feels like? pics.

I recently installed a GM crate motor in my truck. I had to put the Vortec on hold for now. My uncle had this motor setting for a year after it was pulled out of a 72 nova. The best I can tell it has the Eldebrock Performer package on it. #1407 carb, performer rpm intake and cam. He was told it supposedly put out @ 330. I don't know if it is the 260 or 290 hp crate. It definately has a little lope to it, so I can tell it has a little bit of cam. The problem is I can't get the damn thing to hit right on the low end. I haven't started with mains and metering rods yet, but I think that is where the problem is. It stutters and then at about 1500 kicks like a mule. Has anyone got this set-up? Where should I tinker first. I already installed new MSD wires, and I checked for strong spark. Good 13 volt hot wire at the dist., etc. Timing is at 14 degrees. I just know I have driven several cars at 325 HP and it doesn't feel even close. I am just frustrated with it. Any help would be greatly appreciated.
