OK...I got my new 67' Cutty and I have been trying to ID the 330 engine rating. I have read some conflicting comments on how to ID which engine I have...I found a machined stamp on the passenger side cylinder head that reads W 44370 L and thought that W meant it was the high compression 320 HP...but the "L" also might indicate the low compression 250 engine. It is a 4bbl Can anyone help?

Thanks
