Cam swap?
Ford manuals claim that the 2.0L duratec has a higher lift intake cam than the 2.3L duratec...
If thats true, then a simple swap could net a few more hp right? Anybody done this? I was honestly comparing the duratec to another engine and wa surprised to stumble on this...

Re: Cam swap?
what ford manual are you lookin at. i am a ford mechanic and have access to fords online manuals.
directly out of fords workshop manual Lobe lift — intake 8.24999 mm (0.324 in) Lobe lift — exhaust 7.80007 mm (0.307 in) thats on a 2.0 duratec Lobe lift — intake 8.24999 mm (0.324 in) Lobe lift — exhaust 7.80007 mm (0.307 in) thats on a 2.3 so according to fords online manuals, the cams are the same lift. so you would be wasting your time, according to fords online manual.

Ok, most be some bad information I was looking at. I figured it was not that simple, but you never know... Added displacement would surley increase power, I just didn't know if ford pulled the valve lift back to limit hp.

Re: Cam swap?
replacing cam's does not change displacement if I am correct. it was the deck height?

Re: Cam swap?
technically its the longer stroke of a 2.3 that increases displacement. but the taller deck height is there because of the longer stroke.
