Thread: Leyland 4.4 Terrier specs

didn't they also have 4 bolt mains and a forged crank ? or was it just 4 bolt mains ?

I once had a chat with a p76 nut who had used terrier truck pistons in his p76 engine as a performance mod so it seems that some things may be interchangeable.

AFAIK P76 and Terrier were the same except for pistons and bearing material and maybe cam.
But I think the block, heads etc were all interchangeable.

I once read that volvo piston's were the go as they have floating pins and are forged.A P76 nut I talked to at a car show told me that was one of the tricks they use in hotted engines. Pat

I was also wondering if the Z86 oil filter which i have to wait a week to get is interchangeable with the z9 which i believe you use on the 3.5??

I had the rover timing cover on mine so used a z9 filter

I have a terrier in the range rover. Do a google seach and outer limits have a bit of info. Its a lower compression engine with more torque. Depending on who you talk to its better than the p76. Heads from a 3.5 are better. 253 holden pistons fit. The engine can be taken to 5L. Parts are available.

Nope, different thread.
