273 to 360 swap. same converter?

Oh, I don't know. Torqueflights are pretty tough. But the 6 cylinder rear end would give me grief long before the trans would fail. I can just hear those spyder gears bang when I nail it from a dead stop sometime! I'm going to need a 8 3/4 rear end before I get a thousand miles on it. This car is like an onion every time I peel back a segment there's another segment. Oh well! I'll finish it sometime.
