Different size torque converter knob 170 vs 225?!? Are you kidding me?

The difference isn't 170 vs. 225, it's that the torque converter nose and crankshaft counterbore were enlarged for the '68 model year.

You cannot put a '67-down torque converter (with small nose) in a '68-up transmission; you'd also have to change the input shaft and some other parts.

Sounds like the 170 you want to put in is in fact a '60-'67 engine (or at least has a '60-'67 crankshaft).

Thank you for this information. I think you just saved me hours of searching and who knows how much money on a torque converter that wouldn't have worked anyway!

Seems like I'm out of luck with this engine, huh? I'm not going to replace the torque converter AND the transmission (or any part of it) in order to have a replacement engine to tool around in while I rebuild the 225. And there's no way I'm tearing into the 170.

Bummer.

Anyone have any creative solutions that I can afford?
