If you were building a special a Reliant engine makes a good and cheaper alternative to the standard A7 engine, fitting a Reliant engine to a standard road going car will give better performance but will devalue the car in the long run.
I can't comment on an A8 or SV engine, but to fit a Reliant OHV in a A7 you will need to fit the engine quite far forward and above the chassis rails or modify the sump pan to use the A7 propshaft, you will need to make new engine / gearbox mounts, exhaust down pipe and fit a pedal box for the clutch the bulkhead and floor will have to be modified plus you will need to convert 12v electrics. These mods are not to difficult to do and do make a Ruby more usable in modern traffic, but unless you intend to keep the car long term or you are in need of a new engine it's probably best to keep it standard.
