Using serp ancillaries on none serp vehicles
Range Rover Blues:
AFAIK the serpentine RRC engine, called the interim, used a P38 block with smaller journals same os the RRC crabk, but with the P38 oil pump/front end. The only big difference is that the P38 didn't have a dizzy (not sure if that starts with the first P38).
the crank should be the right length already, the camshaft IIRC needs the dizzy drive gear fitting. You can't use a duplex timing chain though, i've seen simplex roller chains but I'm not sure these are still available.
You can also use the older front end if you fit a spacer on the crank under the pulley bolt.
IIRC there are 3 types of crank, the older one is shorter then the interim is as long as the P38 but I think has a shorter woodruff key, the P38 also has bigger jouranls to make it stronger (and generate more separation with a thinner oil).
Anyhoo, your engine should work fine with any front end, the older 4 belt, the LSE 4 belt, the interim serpentine or the P38.
If you need more detail I might look up the title of a good book I read once.

You *MAY* find that the oil filter gets clouted by the diff with a P38 engine in it, I have recently completed this conversion to my RRC and after the first green lane I tested it on I found it dented in by ~15mm, didn't leak, but was very very close to!
The fix is a remote oil filter kit, so budget £80-100 into the build.
Range Rover Blues:
I need to check that then, because I thought the interim engine was basically a P38 with a dizzy.
Bowie:
The quick check is to see if the oil filter hangs almost vertical or not, the non-serp 3.9 points forward at quite an angle, whereas the full P38 serp points almost straight down, hence the problem.
And no, there aren't any shorter filters available, and I wouldn't use them anyways, given the V8's need for good oiling.
automania:
Well i'd just decided to go the serp way as I've got the cover etc , but after Reading about the oil filter thinknim gonna have to find an interim cover, persumably the sump is different too so I'll need one to go with that. Cheers guys for replying
