S2A109RAG Posted November 8, 2013 Share Posted November 8, 2013 I have a refreshed 3.9 V8 which I have just about finished MegaSquirting. Now the Engine has had some work done on it and I have pulled the front off to replace the Cam ect. The Issue I have is the cam I have is from my old dead 3.5V8. This is an aftermarket cam which was magic in the 3.5 but I have a feeling that it is not quite right for the 3.9? is this true? Is there a 2deg difference?

Chicken Drumstick Posted November 8, 2013 Share Posted November 8, 2013 Well what cam is it? If it's a stock 3.5 I wouldn't use it in a 3.9, but then I can't really see the point in using a stock 3.9 cam either when there are much better options out there. Is yours a serp 3.9 or a Vee belt? Not sure, but a nagging thought that at some point the cams aren't as interchangeable. Quote Link to comment Share on other sites More sharing options...
S2A109RAG Posted November 8, 2013 Author Share Posted November 8, 2013 Its a VBelt 3.9 V8. The 3.5 cam Is locally made one from down here ( New Zealand ) I think I will Just buy a new Cam. Any suggestions? Its in a RRC for off road use..... Quote Link to comment Share on other sites More sharing options...
Team Idris Posted November 8, 2013 Share Posted November 8, 2013 Mines ground for torque, (piper max torque from RPI). Better than standard, with nothing surprising happening, is just where I wanted to be And it seems to do that, but my old standard cam was so bad it's hard to tell how much it is better?

Rangy35 Posted January 8, 2014 Share Posted January 8, 2014 I would like to give some feedback about the cam I fitted but my Rangy is not on the road yet to give input. I got mine from Camtech in Sydney Australia, billit cam and very good price and service. But like I said did I make a good choice.......only time will tell.
