I want to make the disco roar!!
Range Rover Blues:
The 4.2 will take a bit of a skim too, the compression ratio is below 9:1 unlike the 3.9 on which it's based. They share the same dizzy BTW.
did you know the 4.2 (4275cc) has ther "iceberg" crank? nice and strong.

already been done ;) alongside a wee bit of port work and a flywheel skim. just before i brought it the chap had a NOS lucas dizzy on it which i have stowed away as i have the mallory on it. And yes i was told by a mate that they (land rover and JE IIRC) used the iceberg castings as the base for the 4.2 crank.
I still smile uncontrollably when i leave in my wake any chav who thinks he can annoy me by trying to mate with the tow hitch.

Yes it was John Eals who developed the 4.2 engine for LR. Annoyingly I had a near new JE 4.6 with ECU in a RRC that was tolen from our unit a couple of years back. Blue would have gone like stink with that in it.
Unless it suffers form a dropped liner, the 4.2 will go on for longer than most V8s and can be economical (all things being relative).
