Hi, I am selling a complete big block ford carb to pan... never neen fired. Can have engine dynoed for serious buyers... its 604" with 3 stages of nitrous that have been flowed and have custom tuneups by speedtech. In natural aspiration on a conservative dyno should make 1050 to 1100 hp, but will have dynoed. For more information please send me a p.m. Thanks asking $18000
