* All cam timing figures are the high rpm lobe. All figures from Honda, which are based on 1 mm (.0394") lift at valve
** Block height measured with steel ruler from deck to bottom of oil pan rail.
*** It seems that the above engines do not all have the same rocker arm ratio! That means the same cam will have different lift at valve depending on which rocker arm is used.

People always ask if parts are interchangeable between the above motors. The answer is yes on most parts (valves, valve springs, cams, rocker arm, crank, head). There are only few exceptions like all intake manifolds are interchangeable except B18C. The tranny's for the above motors will also bolt up to each other. But newer ones are hydralically operated while the older ones are cable.

Too many people are getting fleeced by less than honest wrecking yards these days. So please if you are planning on doing a B16A swap write this down!!!
