I have a 258 with a Holley 390cfm 4barrel and Clifford intake and headers. I'm chasing a hesitation under hard throttle, my air fuel ratio meter reads lean when this happens. I have a 35 squirter I jut installed and 2nd biggest cam and it still hesitates. Any ideas? Holley says if I go any bigger squirter I need 50cc accelerator pump, is anyone running that 50cc or am I going in wrong direction?
