The He 277 was an He177 modded to carry four engines, The He274 was

was much interchangeable?

They seem to have derived from the same He 177,

The He 277 (also known as the He 177B) was a 4 engined He 177; it was
'engineered' in Heinkels Vienna works. It used conventionaly
supercharged engines and was pressurised. It was not supported by the
RLM and was somewhat of a hidden private project but when it was
finally supported was they demanded immediate production. Production
was cancelled on Jult 4th; along with a lot of other projects
presumably due to the allied landings. The aircraft was flown and have
very positive evaluations and very good performance: speed

It was impressive aircraft with a speed of 354mph and range of between
3700 and 4300 miles, it was pressurised and heavily armed with remote
controled turrets; in every way comparable to the B-29.

The He 274 was also 4 engined but it was engineered specifically as a
high altitude bomber in Heinkels French works. It used V12 DB603
engines with turbo superchargers. Speed was about 360mph.

The obvious similarities include the central fueselage and
undercarriage. Wing span was slightly different.
