Now understand i hate fuel injection. 1 because if I put a 610 lift cam in my 91 she aint gunna run with out a stand alone. 2 because a carb is cleaner. The DP head out flows the D port head. I aint gunna argue because the fellas at racer walsh agree with me. knowing that it would seem you could get more power out of a DP head right? So who makes just an ignition controller ? MSD does but will there DIS ignition run without the factory ecu? if it can its simply a matter of welding some holes on the lower intake and making an adapter for my 500 holley hehe.
