Allright I am thinking about the 700R4 upgrade. What did you do to yours to make it live before installing? I understand 88-89 were the best years to look for. I would like to be able to withstand 350-400 hp small block (just a dream). If I get a running one that feels ok what should be done? I would like for this to last but am also looking for the least expencive way to do that

.
Thanks in advance...
I have a 400 turbo no but just something about that lower first gear and overdrive

Oh yea what about the torque converter. Do you need or use a stall with the moderate hp engine?
