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.
Thanks in advance
