Hi Murph..I just finished dyno my 350-255 SS engine. I"m using a hooker 3 step headers with hooker collector and 11 inch extension on the dyno only. i switched to the burns collector and to my surprise no horsepower gain but a 3 pounds of torque gain made on average and then the 11 inch extension was added and no additional gain... I hope this helps...what type of header are you using?...Luke SS 311
