i have a 69 camaro with a 350 bored 60 over, bowtie heads, edelbrock victor jR. intake, holly 670 street avenger carb., msd pro billet dist.and ignition, i was wondering why my car starts to bog down when i slam the gas from a stopped position. It makes a puttering noise. Any ideas. I appreciate the help.

First of all you have too big of an intake. You need a dual plane intake. You didn`t list your cam. Your carb may need some tuning and your timing may not be set properly.
