When I put the gas pedal to the floor the car bogs down and I loose power. The set up I am running is a 302 with a cam, headers, hi-rise shelby intake and a holley 650cfm double pumper that was new as of last year. I have the carb set right when the book told me (about 1.25 turns out from all the way it)and have tried richen the gas/air mix a little to 1.5 turns but this shows little improvement. Do I need to richen more? Jet up? Get a samller carb? Vaccum readings are good and the timing is advanced a little. I also run about a 100 octane gas. the motor is good. Any help would be great.
