I am guessing the correct length heater hoses were too much trouble?

And the correct air cleaner

I assume they increased the compression when the engine was rebuilt for a few more horses? Dyno numbers still seem low.

Being an 03B it is a little early for the shorter heater hose routing. The earliest I have seen with this hose routing is 03D. Anyway sometime around March April of 73 the hoses did get shortened and routed similar to the hoses on the subject car; about the same time the 73 headliners changed. The short hose configuration was the norm in 74.

Thanks for the info, I learned something today! It does have the board style headliner.
