camshaft HRC 1619

Hello,

I'm rebuilding my 3.5 V8 engine. The camshaft which was fitted had the number HRC 1619. I think it is a 3.9 camshaft.
Does anybody know if it really is a 3.9 camshaft. I heard it will give some more power.

I know this post was 14 years old , but , in case anyone else comes across it :
I have a 1995 LDV400 van factory fitted with the 3.5 twin carb ( 10 bolt heads & low compression ) This is the cam that's fitted to that , so it's not a high lift - may well deliver power in a completely different range as the van's a 35CWT . I did note that elsewhere on this site someone else had this cam in a Range Rover and the engine had a sticker stating that ETC 6850 camshaft was fitted . Hope this helps someone .
