It's one of the 'Billancourt' engines (845cc and down), so not a 1.1.
The 'Cléon' engines were 852cc and up - most frequently 1108cc. The 852 engine is rare outside Spain.

The first 1.1 engines in Renault 4s did appear in 1975, but not in 'cars' - they were fitted to R2370 and R2430 vehicles (the former eventually became known as the F6).
The first 1108 engines were fitted to 4GTL cars from January 78.
