345 vs 392IC

Ok. I must be an idiot. None of the parts much up. Bolted the bypass on. The top neck that came with truck does not bolt up,only one of the 2 holes lines up. The top neck that came with my part motor is even more off. What am I doing wrong?

Ok. Got the upper water neck figured out. Mil showed me lol. Amy ideas for the hose coming from bypass?

 

[FDChappie]

Now I see why this is so confusing. Every IH I have seen has a hose flange to match the bypass right where your 5/8" heater hose fitting is. I think you will be wanting a new water pump housing.

Also make sure the bleed hole in the bottom of the bypass housing is clear. And use only a Stant thermostat so the bypass is plugged when it opens.

Ok. How much of a pita is it too pull everything off to replace it. I have a water pump cover from a 392 from a medium duty. Can I use that?

 

[1hc72]

Is the the correct one?

Take the bolts out of your t-stat housing and then set the upper water neck in place and aligned with the holes that you have bolts going through now.

Got it thx

 

[FDChappie]

That looks like the correct housing.

Ok. Huys, pretty much got everything buttoned up. Found a few things that I'm not sure on.

Found a tag on me front axle not sure if it's 4.11 or 3.73
Rear axle says 80 or 60 and c32055 any ideas?

Ok guys did some more work on the truck. Found a few parts thst I need. Throttle return spring, bad hose from intake to brake booster (the one from my 345 intake is to small for the 392 intake), and one more port I'm. It sure what it is.
