600 holley carb pops on acceleration
Hi, I have a 68 camaro, automatic, with a brand new 356 chevy. A cam with 410 lift and and torker intake. I have a 600 holley carb with a brand new power valve. The car runs very well. Valves set and the timeing advanced to specs. Only upon VERY HARD acceleration does the poping happen out the carb. We also have headers and open mufflers.
The idles screws work properly, and thr floats set correctly.
Any advice?

Thanks in advance

Is the accelerator pump arm set correctly? is the pump cam in good shape? are the squirters open and spraying? Is the power valve correct for your application?

It sounds to me like you have either too much or too little jet. Find out the Holley recommended jet size and use those. You can go up or down no more than 4 jet sizes.

If that doesn't work, you have clogged air bleeds. Clean them. They are the small holes in the air horn.
