Welcome to the site. Sounds like the car is in good running condition!
If its got a rebuilt engine and is running good, no need to swap out the 7 bolt! They are very capable motors. Save the money spent on motor+swap and buy some parts!
Cory, a tech here at STM went 10.9@126.8mph on a stock 7bolt with over 70k miles on it!
Check out the video I made of his car last year.
Corys Team STM 2G Talon goes 10.94@126 STOCK MOTOR - Car Videos on StreetFire
Any other questions or need some parts feel free to call us, PM, or email !
