Oh sorry i imagine that might help. So Ive never rebuilt a motor but i have done motor swaps and torn parts of motors apart and fix them. As far as money goes I,m on a tight budget. But not driving the mustang I,m saving quiet a bit so i was hoping 2000$ to 3000$ would get me some where close to the 300hp mark. My car already has AC and smog delete, CIA, tri ax short shifter, king cobra clutch, full exhaust and 410 gears. The condition of the motor now is good when i bought the car the owner said he put a newer motor with 80,000 but he had no proof, so the reason for the rebuild is for my own reassurance.
