Turbo400 is a good trans. Can be built to hold a lot of power pretty inexpensively. The same could be said for a properly built torqflite. The benefits of installing a 400 into a B body, are not... for most, worth the effort. I understand being soured on parts. But It seems that maybe you would be best off to step back, take a breath, and re-evaluate your choice of trans builder. I assure you you are not making enough power to need to walk away from a TF.
