I bought this at a junk yard a long time ago, maybe 25 - 30 years ago. The diverter valve is the right part number for a 390 / 427 / 428 CJ. Did the 302's use the same one? The S - shaped hose looks correct for a big block, but the other hose looks like the one for a J code. What do I have here?
-
A couple more pictures - are the hoses date coded?

Yes the 68 J code also used the three port version of the diverter valve

Yes I believe so but have not taken the time to try and decode the pattern

Thanks for the reply Jeff. Looking at pictures of J code cars the hoses don't seem right. I looked here:

So it is still a mystery as to what the hoses fit.

That long hose has the right shape to be the correct passenger side hose for a FE application but hard to tell if it is long enough from the photo. I don't know what that other one is.

aug 3 1967 date on hose this smog came of a 390 i think.

I see in the 1969 engine assembly manual that a PI engine of that era used a passenger side hose similar to the CJ one but shorter. The check valve is located at the front of the head on a PI and at the rear on a CJ. So, if that hose is too short to be a CJ style setup, it could be PI.
I don't have any 1968 manuals to look at, but the engine assembly manual shows all the different Thermactor configurations.

I was focusing on the valve rather than what the whole (hoes and valve) may have come off of if they originally were all together as shown

Guess length would be the next for identifying each hose individually The longer hose could be from a small block or big block depending on application (model car) since we can't be certain of that at this point

That makes sense, I bought a bunch of parts from Rory Matlock back then, including some 428 PI blocks and cranks and various parts. It's too short for a 390GT / 428CJ RH side, but if the check valve were in the front on a PI then it would be the right length for that.
Much appreciated!

Add 1968 F-100 with manual transmission, as another possible source.

Yes! In fact, I bought one of those setups.
