2 Engine Swap Options - Advice?

[greywurm]

Alright, I'll stick with the th350 that I have. Just need to figure out where it's leaks are coming from then. I have been suspecting the pan and the cooler lines.

I guess the best bet is to use the fly wheel and torque converter that I have in the 250/th350 setup instead of what is on the new 350 motor now? I didn't know if the TC's would be different... But if so, I just need to get the stubborn bolts holding the TC to the fly wheel off. Any tips on that? I am suspecting it was installed with thread locker. Its not like I can drill them out with a screw extractor...
