509 bbc fuel prob.

helo i have 509 cu.bb2extra enderley 110 pump 8hat lines 2 blower lines 8port.running k style barel valve 15#of boost.7al.with hvc coil.20th plug gap ?were should my hat &port lines be in size to see if in ball park.thanks. sam spires.

 

I am not an expert or a "tuner" by any means but I would suggest to put in 55's everywhere and read the plugs from there. Do you have a fuel pressure tell-tale guage to see the max fuel pressure or a data recorder?

 

thanks mike you have ideal where you would run nozzle size hat&port.just to see if im in ball park.very appreciated.

thanks mike running 61% inthe hat in theory how much total area is the motor capable of burning with ign. setup i have.?

 

All of it. But you should set gap at .015. You sure you have enough timing in it? ~30 degrees with the zero mark Verified?
