Hopefully some of this will point you in the right direction, at least... IHC built about seven V-8 gassers in 1964. I notice one of these has what appears to be an oil-filler tube mounted on the front of the engine, I wonder if this is unique to one of them?

Here is a screenshot from the Wikipedia on IHC engines, it has a specific section on gas V8s... nothing about identification, however.

This link indicates how to identify 304 and 345 CID variants in the Scout... I'm kinda thinking the engine ID pad noted in the article may be universal to all of IHC's gassers? Like perhaps that area on your engines may read V-392, V-404, or V-446? FWIW, I'm thinking most of these buses got 345s... I believe the bigger engines were reserved for the larger trucks. But if you're lucky enough to find you have a 392 or larger, you may have a very desirable engine, depending on if anyone is looking for one.

Hope that helps!

I think this bus was posted here before as a potential buy and the consensus was "run away".

It is most likely a 304 or 345.

Does not look any worse then mine when I started so see no reason to run away.

The 392 is unlikely as it was not at least a standard offering at this time in school buses. Also at this time it would have been before they sorted out the cooling issues. I had one and gave up on it after it melted two pistons, and put a 345 in instead. The trouble was hot spots on the cylinder walls because coolant flow between the very close cylinders was not sufficient. The 392 was the largest that started with a 266 in the same overall size block. The later improved cooling 392's were good engines.

I think that "front tube mounted oil filter" is the breather cap on the oil fill tube
