Hesitation/lack of power

nwebber · 05-01-2016, 01:10 PM

Looking for some ideas on the cause. Car is leaving very lazy and has a hesitation at the hit of the throttle. It cleans up and runs strong after about 4,500 in first gear. Tried a spare carb, but unsure if it was good or not, and had the same results. Swapped converters to a known good one and replaced the ignition coil. The fuel pressure is staying steady at 7 1/4. The car is a 72 454 Corvette running in C/SA. The motor is fresh/new and was dynoed. Neither my carb or igntion were part of the dyno testing. Both sat for about a year without usage. Let me know if you have any ideas on what to look for/test. Thanks
