129 Exhaust - Thread Size?

Thinking about adding a stack while it's all apart anyway. Can someone let be know that thread size at the engine?

Thanks. NPT is tapered pipe, yes?

National Pipe Thread, yes.

You might also need a locknut for ridged conduit.
At least I think that is what IH used.
If your using an elbow in the block versus a nipple then an elbow.

Don't know much about stacks but you WILL have to re-enforce the stack with added support. This topic has been talked about before & all stated that.:BlahBlah:

Nik,

Not sure of the layout quite yet... but there is a lock there now. Depends on the rust situation which of those two I'll try.

Nik,

Yah, I've seen those discussions here and there, thx. Again, not sure what I'll do but, fortunately, there a million pics out there to help me decide.
