Todd!!! I think I found out where I lost HP! I went over the engine build in my head step by step and realized that in trying to be anal about everything, I reversed crank direction in my head and actually retarded the 98 cobra cams. I used slighltly smaller keys (about 5mm) and thought I advanced them, but, actually retarded them as far as possible in the keyway. I'll advance them this weekend. I'm curious as to what the hp loss would be doing that. Dynoed 288rwhp w/4R70W.
