I have a 1970 single cab that was converted to a type IV engine. I don’t know of the condition of the engine but before I even get to that there are other issues that need to be addressed. The braking system was converted to the later style with discs up front and is missing several key components. The nose has rust on the inner bottom pieces. Lastly it was an out of state vehicle that I need to get registered in CA. To register I have to get it weighed and inspected, which consists of a brake check and signal lights.

Ideally I would like to do the braking system first and get that up to par so I can pass the inspection and get it registered. From there I’d like to get it into a body shop to repair the nose. I figured that while it’s at the body shop I could refurbish the type IV motor (assuming it’s decent) and swap it back to a type 1 motor I have in a ghia that is currently sitting.

Long story short; will the ghia engine be plug and play? By that I mean, if I need an engine carrier bar, will the ghia have one and be compatible? Will the wiring also be compatible? The ghia is a 74.

Is there anything else I need to consider or other parts I will need?

If the case is not tapped for the rear carrier they sell a adapter that bolts to the oil pump, other than that the throw out bearing may need to be looked at. I would go to the inspection station and tell them what you have because of the age the type 4 may be ok it will just have to meet the emission standard for it's year.

I guess I should have clarified a little more. I would be taking the engine and trans from the ghia to put in the truck. The type IV engine would remain in the truck during inspection but swapped before going to the body shop so I can work on the type IV.

Hello,
Why go through all the hassle.
I don't think the ghia trans is the same as a bus trans.
And, they can push the SC around pretty easy without the weight of the engine in it.
Yet, it's your bus, full steam ahead boys...

No Ghia transmission will fit a bay without drastic modification and adaptors, the type 4 also uses a longer input shaft so on top of the rear carrier you'll also have to deal with that, and as mentioned the clutch may or may not be compatible.
Sounds like work to me.

It’s temporary and would allow me to use the truck while I work on the engine and allows me to get it to the body shop as well. I understand the type IV is a better engine, I just need to know if the reverse swap will be plug and play or if it will require a little or a lot of work.

If the ghia trans won’t work, I do have a 002 trans but it has a 091 bell housing and nose.

The trucks trans will have to be used with the Ghias motor but you will need the rear hanger adaptor to hang the motor (classifieds or ebay). 70 Bay used the type 1 so the Ghia may need its throw out bearing if the Trucks was changed for the type 4.

The tranny input shaft needs to fit the engine and not the bellhousing. You would need to swap in a Type 1 input shaft and then later when you put the Type 4 engine back in swap back to the Type 4 shaft as well.

Before going to all this work be sure that CARB is going to accept the Type 4 engine being in an earlier van.

The wiring should be pretty much the same if the Ghia has a Alt. in now or now is a good time to up grade it, The trucks Alt./Gen. wires, Coil and wires to dist. and carb. from it, and oil pressure wire should all be there, any extra for the type 4 just label and tape off.
