Simple as this: Your speed is really low and suggest even with slicks you don't have the power to get out of the 14's. Whatever the problem is, it's costing you about 80 horsepower. You DO NOT NEED MORE, like a manual vb, or 4.10's to fix your current problem. My stock 318 4bbl with stock manifolds and 2.94's would be on your quarter panel to the finish. Your set up should push deep into the 12's. Swap a different carb on of 750 cfm's. eddy or holley dp. One drive around the block will let you know. When you find your problem, you'll think you dropped in a new motor. Yes, it will be that obvious... Good luck
