From the book, you and your Range Rover (Haynes)

V8 3.9 1989-1992 3,950cc 94.0 bore x74.1 stroke 188bhp@4750 235ft/lb @2,600rpm 9.35:1 compression ratio

V8 4.2 1992-1995 4,278cc 93.98 bore x 77 stroke 200hp@4,850 250ft/lb @3250 8.94:1 comp ratio

RPI website may be of some help for the physical differences

Forget that 'cause I just cross referenced it with another book and they do not agree  :?

Range Rover ,the first generation states

BUT all other info tallies  :?

Confused

The 4.2 is a stroked 3.9, that's all.  The CR is lower but off the top of my head I can't tell you exactly.

BHP is just shy of 200 IIRC, 0-60 only just over 10 seconds with a EEC kerb weight of 2100kg or thereabouts.
