long story short, changed out a 350 to 400 sbc. went from a to a3 impeller and am not seeing any difference in performance, turned the a at 4000 turning the a3 at 4100. Problem is at the same time i put in a different grate, inducer, changed from a jc bowl to dominator bowl and a best nozzle.
so far i have taken out the grate and ran it no difference , removed the inducer that got rid of some of the slip at take off but no change anywhere else.
someone has to know if the dominator bowls just dont flow as good as the jc or if its the nozzle that sucks... any help would be appreciated. thanks
