range rover engine

Unread post by churchy » November 10th, 2009, 2:07 am

i had my p76 block drilled to take range rover heads but the guy at the shop said i should get the p76 crank machined down insted to soot the 3.5 block as it has shorter rods and will hold together better but i am woried it will have to much compression it is also going to be fuel injected any input would be appreciated thanks.

Churchy Hi. It sounds as though you're getting into real technical territory with that motor , sorry I can't help with that stuff , but I do remember that 20 years ago that was the V8 motor to use in speed boats because of the HP they could produce .

If you are in NSW there is a wrecker out at Silverdale who mostly wrecks Rover 4x4's , they may be worth a call , "Land Vehicle Spares" , you can check them out on the I-net at Australian Land Rover Owners

from what im told the p76's have the issue down the bottom end.
theres a bloke on here who had a an old 2door with a p76 in it, later on down the build up he put 3.5 heads on it and ran the standard twin carbies. didnt have much bad things to say about it after.
so sounds like your onto a good thing.

I just bought my first rangie, it's a 83 with a 5 litre rover engine in it. (p76 with 3.5 heads) not sure how they get 5 litres if it's got a big bore or bigger stoke anyone heard of this before?

If it's a P76 engine - doubt very much that it's a 5 litre. The P76 V8 was 4.4 litre, and I seriously doubt if there was the capacity to bore them much beyond this. The only 5 litre version of the Rover V8 was used in TVR sportscars.

I had a P76 engine I rebuilt to 5 litres. I had the liners pressed out the block bored, new liners fitted and (from memory) 202 Holden pistons fitted to suit the new liners. I just ran the standard ww Stromberg carb jetted to suit. The engine pulled like a train and almost had the same performance as my mates 350 chev in a landcruiser. Never had any problems with it.

My previous 2 door had a P76 motor taken out to about 4.6 and my current one has been taken out to 5L. Mated with the LT95 with the higher ratio gears is a great setup. Carby setup is always an interesting one. I used to have a manifold that had been modified to take the twin strombergs to replace the Holley as it was useless on steep inclines.

To run the twin strombergs, you're either going to have to fit manifold spacers with the rover manifold or machine the P76 manifold to take the carby's you are wanting to fit.
