I haven't done this with a Riley ... but, this is rather common practice
on MGAs. Assuming the MGA commonality ... the Riley flywheel, front
plate, and back plate should bolt right up the 1800 block ... as well as
the intake and exhaust manifolds ... and, the 1800 spigot bush (crank)
should accept the tranny input shaft. I'm not certain which water pump,
pulley, and fan combo that the Riley is fitted with ... so, you may want
to check them against the 1800 bits to insure that you have adequate
clearance between the fan and radiator.
