Big block stumble
Have a "72" 460 cu.in mildly modified vette. I have reacently installed a jet perf. Stage 2 carb. And the tech guys told me i need to install a high flow fuel pump with a regulator to keep the fuel at or about 6psi. They also told me that i did not need to hook back up to the factory fuel bypass line?? Which i have done. Now i am exp. A bad stumble when i wind out first and shift into second. Does anyone know if this bypass not being hooked back up may be causing this issue??i can not seem to find any info on why this bypass line is even on the car. Thanks
