Type IV heat exchanger interchange
My engine builder was unable to secure decent heat exchangers for Ludwig's new engine so now I'm shopping.
I know there is the oddball 1979 square port type, so those are out. But what, really, is the difference between carbureted and fuelie heat exchangers? I suspect fuelies can't use carbereted exchangers, but can a carbureted engine use fuelie heat exchangers? Is it just the matter of the f.i. exchangers having some sensor that could be left idle?

Here is some good heat exchanger info.

Was your Ludwig that is being replaced/rebuilt an actual 1800 '74 type 4? And if so, do you have all of the tinware? If so, getting good used/new '72-'74 HE's is the best way to go.

The heat exchangers themselves don't have any FI sensors. As far as I know, and please correct me when I'm wrong, the only differences are the shape and configuration of the inlet and outlet flanges. Here are some pikchurs, courtesy of The Bus Boys.

The builder machined the AMC 1800cc heads to conform to their new lives as 2.0L heads (the case itself is a GD). Since all the changes were internal, I'm assuming that for fitment purposes this is an 1800cc engine and all the tinware I have--which should be all of it--will fit.poptop tom wrote:Was your Ludwig that is being replaced/rebuilt an actual 1800 '74 type 4?

Yep, that looks like it tears it. The Bus Depot site doesn't have pictures of the later ones, so I couldn't figure it out. I always forget about Bus Boys.dtrumbo wrote:The heat exchangers themselves don't have any FI sensors.

Yes, a poop load of a lot easier to seal. Heat exchangers to the heads and muffler. No funky j pipe, etc. It's on my to do list when I ever find a decent used pair at the junk yard. But then I'd actually need to find buses in the junk yard. Haven't seen one in a year now.LiveonJG wrote:Also, less parts make it all around easier to deal with.

Re:
THANK YOU! I have seen these drawings and always thought "man, if only I could have the names instead of these letters, it certainly would help me learn the name and make it easier to communicate with." Well the answer was Bus Boys. I didn't know these dudes existed and that the info was there. Thanks again. This makes a huge difference. I know this is the technical forum, but I had to share my excitement.dtrumbo wrote:The heat exchangers themselves don't have any FI sensors.
