Ok guys I am a new user and need some help. I have been out of the hot rodding scene for a few years and I have recently aquired a new toy. I want to tell you guys what mods it has and what the problem is and see if you can help me with diagnosis of the problem. Ok then...the car is a 1993 Mustang GT convertable. The car is equipped with a automatic w/overdrive tranny. It has 64K original miles. Ok the bottom end is stock ads are as follows.....B303 cam, trick flow intake with 1/2 inch spacer, 73mm C&L mass air meter, Mac 1 5/8 long tube headers, Flow master american thunder exaust w/mac off road H pipe, 4:10 rear gears, BBK 70mm throttle body with spacer, BBK 255L fuel pump, Aluminum radiator, electric fan, BBK cold air intake and K&N filter, BBK adjustable fuel pressure regulator, MSD cap and ford racing 9mm plug wires. Ok that about sums it up......with all that said I have owned the car about 3 days so you know as much or more about the car as me....the car idles good with a lope....shifts smooth with a nice shift kit and pulls hard....BUT the car does not run at all as good as it should with these mods. I am guessing the car as it sits is running 14.20s maybe? It seems the car is sluggish out of the hole.....so bad that if I mat it from a dead stop it will NOT smoke the tires. With that said I know that with the RPM range of the B303 cam a stall speed is reccommended and I plan to go that route but the car should still have more that it does and if it was the stall speeds fault then I should be able to run along in low gear at say 3000rps and tromp it and go side ways and thats not the case it will not even if the rpms are up first. I have a couple opinions but wanted suggestions before I start. I feel like maybe either the cam was not degreed in correctly or maybe the timing is retarted to much.......................Well I am eagerly awaiting good quality responces from people with experience with fox body cars.............Thank you in advance for all or any help this might generate.

 

Nice setup but you may want to get a more extreme cam, also the stock heads are very restrictive. look for some GT40 heads, can go lookin aorund junk yards for explore heads(GT40P). As for the cam I'm not much a expert there but get at least a D or E cam. What you would be better off is getting a custom ground cam.

 

Well this is a older post I am guessing a month ago and since that time I
have made DRASTIC changes...........Lets see....Trick Flow twisted wedge
alum heads, track heat intake, stage 2 camshaft, and a Vortech V1 S trim
supercharger.....The car made 445 RWHP today on the dyno with only 8 psi of
boost...............

 

Nice!!!
