First of all let me say that I am new to build mod motors. I have a 03 Mach that I have owned since it was new. Last year I procharged it with a p1 and changed out all of the suspension and running 11.5's in the 1/4 with 465 hp. I am wanting to build a new motor that will get me down into the low tens and still be street able. I know that I will have to change blowers. I am also wanting to go with an automatic. Does anybody have any suggestions that will help me get started .
