I'm pretty sure it's an 1100. From a Clubman, or Leyland prior to sometime in 1975, or 1976. Something like that.

thanks slinkey and doc., shame i was hoping it was a 998cc.

hope the box is good. i'm gonna tear it all apart and re-build it next year.

What's wrong with the extra power and torque?

i like the novelty of a 1L engine.

will this chew up more petty on the long aussie highway straights? or can i tune it right to actually get a better L/100km result then a tuned 998?

also what kind of gearbox would be best for highway driving.

highway driving = constant 95-105kph

My block has a very similar number -- 1015 4582, and I believe it was out of a '71 or '72 1100 van.

I had thought the number was not a standard BMC stamping until recently, when I discovered that that pattern was used in the early '70's vans.

Hope that helps

1015s were used in both 1098 Clubby vans and sedans.

In hilly country a 1098 will use less fuel than a 998 as you don't have to row it up hills with the gearstick.
Either remote or rodchange box will do, use a 3.44 diff if you have one.

They changed the engine number prefix system a few times and that was the first "Leyland" system. The first two digits refer to the capacity and the last two digits refer to the engine spec. After about three years they simplified the system and they were all 1015. I think the change to 1015 was in about March 1974.

I have a 3.44 diff on my 1100, and it's a pretty good all round compromise. Highway revs are maybe a little higher than I'd like, but the upside is that you get decent acceleration through the gears.

On the highway, my car on 165/70R10's pulls about 3,800 RPM at 100 km/h (26.4 km/h per 1,000 RPM in top gear) which is noisy, but the engine is pretty comfortable doing that sort of revs.

what about on flat long stretches? what sort of engine would be best there in terms of fuel consumption?

and what box would be best to go with it?

what engine and gearbox set-up would you use for a trip around Australia on the major highways?

I reckon a 1098 with 3.44 diff would be better on economy than a 998 as it's doing it easy.
The late 998 Clubbies with 3.44 diff are overgeared, IMO. And, they had an air pump and all that pollution crap fitted.
Remember the diff used in 997 & 998 Coopers was a 3.765... and they were much faster, and had 15HP more.

Type of box makes no difference on the flat, as all are 1:1 in 4th gear. What affects your cruising is the diff ratio and tyre diameter.

Andbat, in a couple of weeks I'll be able to give you a really good idea of the highway fuel consumption of an 1100 with a 3.44 diff -- I'm driving mine from Brisbane to Melbourne, we'll be doing 100 km/h max all the way.

thanks sgc, i'd really appreciate it.

i wouldn't mind knowing what head it'll have (and any mods), inlet manifold, carby(s), filter(s), extractors and exaust to?

thanks for the advice doc, i'll hold onto my newly accuired 1100 and get all extra necessary modifications.

ps: ho hard/expensive is it to get an old 997 or 998 3.765... diff?
