[my new 72]

My cam isn't too big. It has just under 500 lift and 110deg. Lobe seperation, a little lumpy, but nothing wild. From what I have read, th eupper RPM limitations are due to flow, and that is why I asked about porting and larger injectors. I also believe it can be converted to to MAF , but that is just what I "heard", so I am not sure. Good tip on the commander system, I will check it out. I'll give my engine builer a call and see if he can give me any advice and let me know what he can do as far as opening up the lungs on this thing.
