The 55.2 was built for a V8. The earlier ones were not and although the blocks are rather small, I think you would still hit the steering box. The engine compartment in a 2 ton is the same size as a pickup engine compartment. The 302 was a high compression, high rpm engine. 11 to one compression demanding very high octane and rated hp at 5800 RPM. It is not my idea of an engine for a 2 ton. The 307 was built for what we used to call "grocery getters". And in my opinion they are better left in the sedans they were born in.
