Compression Ratio

(1/1)

Merlin:
How do you tell whether your C/R is 8:1 or 9:1.  Needing a years supply of new plugs from the Spring Adventure & the plugs are different for the 2 C/R's.--Cheers--Cogs

muddyweb:
It is often stamped on the block just next to the engine number.

(nearside, between the middle 2 pistons)

Range Rover Blues:
Not a cast-iron method of checking but the low compression engines used a dizzy with an external amplifier wheereas the HC engines had the amplifier on the outside of the dizzy body.

Merlin:
Sorted--9:1--found it on the block as Tim said.--Cheers all--Cogs
