It is a 1969 model. l am looking for other US Seat 600D owners.

l have a '58 Fiat 600 sedan, & l also looked into putting an 850 in it. Here is what l was told: You can do it, & lots of people have, but it is not just a ''bolt-on'' job. You have to cut away some metal from the car body to make room for it, & modify some other stuff, & u also have to use the 850 is engine because the original 600 engine spins the opposite direction. l eventually decided to convert mine to an electric motor & nevermind the gas engines. But the bottom line is, yes it is possible & the 850 engine/tranny will add a lot of ''zoom-zoom'' to ur classic car.
