Wanting to sell my 7448 b&b built holly carb. i bought it last year, and ran about 10 shows with it. Awesome carb! all the bells and whistles, came originally off of a nascar pavement modified (whatever credibility thats worth), flows every bit as good as that 800 dollar Keith dorton carb, and will pass every check gauge there is. been checked every race up top, and pulled off and checked twice, no problems! starting asking $375 plus shipping, or shoot me an offer! message here or call me at 620-544-6961.
