I got 40 mpg with the 1600 cc CVCC engine and 35 mpg with the 78 Accord, the only difference was the heat on the intake manifold, 77 had exhaust heated and the 78 had coolant heated intake manifolds, both had 8:1 compression ratio.

16 hp,ouch! 'guess we pay for those steep hatch angles.(still paying with the 2012 VW Beetle!)
Was the 1978 Accord a 'new' model body series or did they just do the engine mods? I've only owned the one Honda,and it seemed like they would introduce a new model on even years and let it run for 4-years.
That's pretty amazing about the significance of the intake tract!I wonder if California NOX standards forced them into the coolant-based system.
