Im torn. Cant figure out if i should stall my 4l60 and rebuild it when it blows....... or put in a th350 and stall fromt he get go. My car has 3.73's in it and when i drive it in 3rd (1.1 ratio) it revs pretty high, kinda crappy for e-way driving. My car is a street car with often trips to the track. Now with a th350, is my car gonna be a little sluggish off the line?? And will it be faster with the 4l60 with the tall 1st gear in thoes trans's?? What are the pros and cons of swapin to a th350 from a 4l60e.
