[88fox120]

Hows it going everyone my name is joe and im from middletown ny. I just bought my first Mustang yesterday and i am ready to go at it. Ive been buiulding hondas for the past 10 yrs and i have always wanted a stang and now i finally have one. Well enough with the small talk and more about the car, Its a 1988 mustang lx 5.0 its already equipped with a lunati 522 cam the heads are ported and polished with oversized valves and dual valve springs, it has edelbrock upper and lower intake manis and a bbk short ram intake bbk shorty headers x pipe and flowmaster exhaust, its an automatic and it also came with weld drag wheels. I quess the car used to be 5 speed so the person converted it to automatic and really didnt do it properly and i need to fix it, if anyone has any knowledge and advise they came give me it would be appreciated.
All information will be great and especially any advice ohhh and id like to know what type of fuel system i should do. Im definately gonna build the motor more i wanna reach some good power gains.
