jagwit Posted March 9, 2012 Share Posted March 9, 2012 Hi guys Has anyone tried the 4.6 Cam (ERR5250) in a 3.9? Please share your findings as I am considering doing so. Here's why: I believe the 4.6 cam will deliver more torque and power in the range 2000 - 5000rpm than the standard 3.9 cam which delivers less max torque, but more evenly over a wider rpm range. I have no evidence to think so, this is pure wishful thinking if anything on my part. Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted March 9, 2012 Share Posted March 9, 2012 I thought the later lumps gained low-down torque through the bunch-of-bananas inlet manifold. Also a 4.0/4.6 cam might not have the necessary drive for dizzy/oil pump. Quote Link to comment Share on other sites More sharing options...
jagwit Posted March 9, 2012 Author Share Posted March 9, 2012 DARN!! You are right on both counts. Dizzies don't feature on my horizon any more which is why I keep forgetting about that little detail. Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted March 9, 2012 Share Posted March 9, 2012 Tell me about it, I'm stuck with a dizzy cam in my 4.6 at the moment which is holding up the swap to full serp front end Quote Link to comment Share on other sites More sharing options...
