I have a tx20 warhawk and a dominator pump, my motor is a 565 bbc 10.5-1 comp. afr 335 heads, cam is 274-278 dur. @50 and 750 lift. I turn a A hi-helix 5500 rpm with a single 1050. my last weekend out with no mufflers and back seat out I ran 98 mph on gps so what started out to do a tunnel ram and dual 4150,s has turned into an addiction!!!!. I went with a profiler sniper tunnel ram and after talking with gary Williams I am going with his dual 1120 dominators and either go with a B or get my impeller cut to get my rpm to 6500. I am also going to change my fuel system to a bypass system. I have also speedcoated the middle tunnel and pump intake and adding a vacuum pump to the motor. so let me have it! am I going the right direction for better performance?
