Misfit Maybe the larger cam and 2 715 holley carbs have something to do with the problem. Is the timing good? Who set the motor up, are the carbs too rich or lean. Fuel pressure OK? Check the basics first then go to a Dyno. Is the cam retarded or advanced?? This will change the motor overall preformance. Need info to help with the problem??? Rick Lake
