EN 707

[james j neiweem]

I see that the EN 707 gasser and the END-673 had almost identical torque (around 600 ft lb. This would indicate that the two engines had the same stroke and bore. Was the block the same for both engines. The 707 must have been a beast of a gasser. Its life was short lived as it came on the scene to late as diesels such as the 673 were coming on line at the time. I believe IH's biggest gasser was the 501. How did Mack's EN 540 flat head stack up against the big White flat heads. Those Whites had a great sound. I am retired now and I have nothing better to do than think up nostalgia from the past.

No, 707 gasser had different block from 673. First thing it didn't have a hole to attach an injection pump, just unbored flat spot. And the 2nd it had larger bore, the kind (or the same?) END711 had. Not sure the crank was similar and the head studs pattern might vary either.

The en 707 was a 707 cubic inc eng same as the 711 and a 5" bore.

Was the original maxidyne block  a 673 block? It seems the 711/707 block was never followed up on.
