The transmission cares more about how much torque is being inputted , not so much how heavy the car is . Now, there are many 455 Pontiacs and BBC running 200THM , so there are many parts available to beef up the weak points . One interesting modification I like is a 350/400 input shaft spline , and modified pump , which allows you to run a 350/400 converter . What is neat is a 200thm was meant to replace a 350 , so the length and output spline is the same . With a modified spline and pump , you can then also use the same converter . I bet there are a few Racers out there that know just how much faster a 200thm is compared to a 350 .
