Just signed up so hey everyone , 1st mustang but been around them , just got it this weekend and it was being built I assume for the track here is whats in it 306 c.i. , Edelbrock heads , 1.6 int. rockers , 1.7 exh. rockers , e303 cam , Edelbrock Victor JR manifold , Holley 670 street avenger , MSD 6AL ign. , Headman headers , H-Pipe , Flowmasters , subframe con. welded , Tremec T-5 , Centerforce clutch , 3.73 gear , and Weld Draglites with new street tires , oh and its an 87 coupe with a 89 gt lower all rebuilt , Idles mean and runs pretty good but not 100% , still needs some tuning , question is do I have too much carb and the wrong manifold for daily street use even with all the other work done or do i need to tone it down some maybe a 600 carb and rpm manifold or will that be a waste to the other parts , sorry so long .
