Thread: 3.5 or 4.4?

Shane

The P76 block is the same angle block but it has a longer bore hence is wider at the valley. Also the heads don't have the accessory mounting bolt holes in the RH head.

The valleys from the Rover and the Leyland are not interchangeable and to mount the standard air con brackets there is usually an adaptor plate on the RHS front of the engine.

The engne number will have commencing number prefix of 440 or 441 etc.

I had a 5.1 litre version of the P76 engine made by Rockhampton Engine Reconditioners and it was more trouble than it was worth. Eventually went back to a Rover engine albeit a 4.6 Rover block.

Hope this helps.

Is there any visual diffrences between a 3.5 and 4.4? if so what are they?

Also I've had a look for the engine numbers and cann't see them any pionters on where to look?

Cheers Shane

Most put the Rangie heads,Timing cover,Dizzy, Sump and Starter with spacer ring on the 4.4. So the manifold(May still have 2 barrel carby,a Rangie stromie set up grafted on or spacers and complete Rangie or Vitesse manifold), Engine mounts and some ancillaries mounts will be the most obvious that you can see. The engine no is at the back of the block
If you have Range heads and T cover it won't give you any grief so long as you don't rev it hard as thay tend to split the block along the cam
Still plenty of them around.

Yes that's correct place for the engine number - I forgot about the difficulty of having to lie on top on the engine and with a mirror attempt to see the number in the little gap between the firewall and the back of the valley cover.

Seem to remember we had the number re-stamped up the front to make it easier to read. Mine had the Rover rocker covers and timing case but still the P76 manifold. The extractors were specially made for the P76 and RR chassis.

Almost anything is better than a 3.5. A 4.4 has some issues, the main one these days is that it is over 30 years old and it is getting more difficult to get parts for.
Between a 4.4 and 3.5, I would pick a 4.4. Between a 4.6 and a 4.4, definitely the 4.6. Iy could go either way when comparing a 3.9 or 4.0 EFI and a 4.4

They made extractors for it They should have used 3.9 efi manifolds they work well
. Ive always been able to bend engine pipes down on them so it will line up again.

Thanks heaps everyone you all have been a great help with out looking at it again i dare say it is a 4.4 just from the air con bracket.

no wonder i couldn't find the engine number.

now the next question anyone have or know where to get a water pump from?

I've tryed the guys at silverdale and a few others and can only get a rebuild kit at a price that i think is abit steep.

Cheers Shane

They didn't make 3.9 EFI manifolds in 1985, the only Rover EFI was the SD1.
