My mustang made 290RWHP and 306TQ on a dyno jet. I was expecting to be at least 315-330 any ideas what's holding me back. I have trick flow 170cc track heat heads w 1.7 Rr, b cam, unported weiand stealth intake, holley 650 dp. The heads were milled to a 58cc combustion chamber and the timing was set to trick flows specifications, the carburetor jets were changed to 70/71 and the A/F was perfect throughout all rpm. The dyno chart show peak hp at 5800 then it starts dropping off! Could it be that I need a victor jr intake, bigger carb (670 demon), or maybe just a carb spacer on my weiand intake. Am I expecting too much from a b cam? Although I have seen a few guys running a b cam make 315-330 RWHP. I plan on adding underdrive pullies soon. At this point I just wanna break 300RWHP. Can anyone tell me what could possibly be holding me back? Also could it be that I need to port match my weiand intake!
