Interesting, because NAPA shows them being the same diameter. After some looking I did discover that 70's V8 stats were all larger. The slant 6 & later 318/360 are listed as the same (I looked at 91 for my checking). The slant 6 I checked specs for was a 77.

1991 318/360 gasser stat:

Both of these were taken from their listing for a 1991 Dodge W250 4x4 truck.

After reading your earlier post, to comment on the t-stat's 'bypass closure disc', technically I can see where it's important. But when I used the small block t-stat in my 90 CTD in my crew cab I was even thinking about it. I used a 195* NAPA t-stat iirc. No issues, warms up normally, no overheating with plenty of towing to 20k pounds.

Ok that's right, Chrysler changed the t-stat housings and stat among many other things after the 70's. My thinking on the 94-98 12 valve t-stat was based on using a late 70's small block t-stat in my crew cab.

I didn't even realize that . .I thought it was big blocks had a bigger one...lol
I wondered how much effect the bypass disk would have looking at things myself, considering the mighty B series & IHC V8 are the only engines I have ever personally worked on that use one and all the others that come without it don't overheat. The MOPAR small block has a huge bypass hose too.

To get the 318/360 v8 t-stat to fit you would have to do as this guy did, sand/grind/shave the t-stat housing or the stat, whatever he did
to fit the larger diameter stat. It is the same diameter as the 94-98 12 valves, and possibly 24valves t-stat. The 89-93 12 valve uses a smaller diameter t-stat.

we did clean out the hosing with a pneumatic brush, just to get some of the grime off and all that good stuff
