Borg Warner T 56
I am currently planning out my future custom rod. right now i am debating on the Borg Warner T 56. i can make mounts and do all the fabrication. i would like to know what the T 56 can handle. i am planning on a potent supercharged small block making about 500 rwh. the truck is going to weigh in at about 2500 pounds. my theory is that with the T 56, i can run 4.56 final gearing or possibly up in the 5 range and still maintain a freeway rpm of about 2600 in 6th gear at 60-70 mph. i am will have the best stuff i can find. anyone who has something to share, i would appreciate it. is there an equation that i can use to find my rpms at a given speed?? thanx for your help.
