The speedo is probably geared for 2240 TPM; apparently you can tell by reading a code on the back of the case....
You need an "A" type 3360 TPM speedo.
You also need the correct size pulley (mine is 3 1/4" OD), but the important thing is that it should provide 1:1 drive from the propshaft.
Then it should work OK.
My pulley bearing was quite sloppy, there's no bush and the shaft appears to be unhardened. I could have done something about it but decided it was OK if regularly greased.
