Re: Attempt/Mistake #2

I am at work right now but I will get you all that when I get a chance. I know it's 11:1 compression, and has a Xtreme Energy 292 mechanical roller. Has a Proform 950 carb ( the fuel/air was perfect when it was dynoed). The shop that I had it at thought that the reason it fell off at those RPMs was because of the 4.5 inch stroke. Seemed odd to me that it peaked at such low RPM though. The cam isn't massive (which the heads woul benefit from) because the truck is street driven. I called Comp Cams before I bought everything and this is the one they recommended. Another thing that was odd to me was that it made max power with only 32 degrees of total timing!! That was before I had the MSD though (not sure if that makes any difference) I would be happy to spend some money on the engine if it would help my power if I knew what to do. I had old trashy 1.5 inch no name headers on it when was dynoed. I have since gotten these 1 7/8 inch primary Hookers. 3 inch dual exhausts.
