Ok first to start the car is a 1995 mustang gt. Car has a lot done to it put down 450hp to the wheels last year on dyno. Vortech V2 supercharger and much much more... Last year tword the end of the season i blew the headgasket on the car. So i pulled the motor installed a bunch of new things just to keep everything on the up and up. Now motor is in and on first start it starts rough. So i broke the distributor lose, pulled the jumper for timing and trying to dial in the timing when i get it close to 10-12 degress BTDC motor revs up to about 2,500rpms and stays there. Also has really bad throttle response. What might it be, also what diagnostic should i do next. Everything seems to be plugged in weather electical or vaccum. NO Oil, Fuel, or Coolant leaks... Please help!! thanks!
