Type 4 engine research project

[888]

I can't find anything stamped on either case anywhere. There was a fan shroud assembly in the rotten bus with an AW code label which should be an 1800 fuel injected engine from a 75 Type 2 so that explains the sensor pigtail, I guess.

The engine in my bus is dual carb, no label on the shroud, no stamped code anywhere. I'm told it stopped running many years ago which is why it was parked. Still has oil in it. Need to get it pulled out and see what I've got to work with.

I also picked up some engines that were supposedly 1.7's but I discovered once there that they were actually CD code 2.0. Since I had already made the trip and they were reasonably priced, I brought them home as well. No intakes etc, just long blocks with valve covers. They do have the printed numbers still visible above the stamped numbers on the case. I'll post photos of those shortly.

So now I have quite a collection to work with. I found a link to a Type 4 decoder @ tunacan.net on the Ratwell site which has been helpful in figuring out the detail on what I've got.

Current lineup:

Whatever engine is currently in the bus. Dual carb, seems like it should be a 72-73 1.7 CB code if it's original based on the reference lists I've found.

CD code spare engine that came with the bus. Should be a 73 1.7 dual carb automatic. 371Q heads.

AW code case (based on shroud label), heads, and misc tin, shroud, fan, etc. from inside of rotted out bus. 73 - 75 1.8 automatic. 371S heads

GD code engine 1 - 76-77 2.0 solid lifter fuel injected. 372G heads, looks like these heads should have sodium filled exhaust valves and be set up for a CHT sensor. Still had oil in it, seems pretty solid.

GD code engine 2. 76-77 2.0 solid lifter fuel injected. (1) 372G 2.0 head and (1) 372H 1.8 head. This one is pretty rough.

I haven't disassembled or measured anything yet. Next step is figuring out what condition everything is in. I'm sure that there are optimum combinations of everything worth working with but that is down the road.

So more to come.

Photos added of printed numbers on the CD code cases.

This is a 1700 head

This engine has 1800 heads and a breather box for a carbureted engine. The distributor is likely for a carbureted engine as well.

If converting/returning to FI, don’t bother finding an “FI” breather box; just plumb the pcv after the box. It works fine and is simpler. You do, however, need a proper distributor.

Question - I have the opportunity to pick up a set of 1.7 Type 4/914 heads casting code 022.101.372. A local aircooled engine builder has already done the valve work to them.

Are they significantly better in some way than the other Type 2 heads casting code 371 I already have?

Thanks!

1800 heads should have larger valves then the 2000, not sure if the 1700 also had larger valves.also when buying heads ,check the exhaust ports ,they may be square ish or round,to match your exhaust.

Thanks for the responses.

Ray, the Marketplace ad is gone now so I can't see detail on the valve work but I don't recall the seats being mentioned. I do have a photo of the heads in my messages and here is no A or B on the casting, just 372 and a space where there usually is a letter. Does that make any sense?

I need to see what heads are on the engine still in the bus but I already have a set of 371Q heads so rather than drive 3.5 hours to get these 914 heads, I'll just go with having the Q heads reconditioned.

FWIW, I've been referring to the archived tunacan.net xref linked on the Ratwell web site. Not sure if it's 100% correct but it seems like a place to start.
