holley jets

Guest

1362 has a holley r477-2 4 bbl mech seconday. Car has al intake with ford emblem it. Smells a little fumy at idle, maybe a little black smoke under hard accel. I am going to remove it and install a kit. Any idea of a jet size? Any recommendations? Any idea of what size the carb is via part no? Thanks

I have not removed the carb and taken it apart yet...I will compare my jet size to your spec. I think you have a good baseline. I run 4 square 75s in a sbc 850cfm drag door car 6.73 1/8
