Shano you would have to replace every other component of the engine if you were going to place it with something other than a 76 Civic engine. Can't think of any engine at all that would fit nicely into the Civic without costing an arm and a leg.
Better late than never, but the 76 Accord is an EXACT drop in. Same block, etc. Just larger bore &/or stroke (I forget which). Same head, carb, etc. go right back on. Identical peripheral mountings, etc. Is only marginal gain (1.6 vs. 1.5), but is something.
