96 141 casting block, is it 3/8" NPT or 1/2" NPT?

I will going to pickup a newly purchased 6.5 engine (supposedly locked up) out of a '96 truck.

It's a complete engine, IP, turbo, intake, etc. etc.

Anyways, I'm under the impression that this will be the 141 casting.

So what size oil cooler line connections does this thing really have?

It's got Dual stats on it from factory...

I'm pretty sure that this block won't have oil spray cooling jets (only reason it's still worth picking up).

The only thing bad about the deal is that it's ODB-II so I can't use the computer and stuff from the truck for my DB2 to DS4 conversion...

OK, I'll settle this dispute!

Got the "research" engine sitting in the back of the pickup from the Salvage yard.

It's 3/8" NPT, just like ALL the prior castings (929, 599, and 660).

I wanted this engine to mainly map out some more differences throughout the years, like where the OPS is located (in the Veeeeeee verses on the back).

Just for reference.
