glentwenty Posted May 10, 2015 Share Posted May 10, 2015 Hey guys, thinking of getting some 4efe cams machined, just wondering what differences there will be once it's been machined. Quote Link to post Share on other sites
Russleh Posted May 10, 2015 Share Posted May 10, 2015 Would all depend on what duration and lift the new cams had compared to the old ones. Dont think there's such a thing as a general machining process. Head would need shimmed as well.Russell Quote Link to post Share on other sites
glentwenty Posted May 10, 2015 Author Share Posted May 10, 2015 My brother was saying something about you get the bottom of the lobes machined or something so the cams sit a bit lower so that when it comes round it opens them up wider or something along those lines, anyone heard of this?

Russleh Posted May 10, 2015 Share Posted May 10, 2015 Yeah its almost like that. The actual camshaft is in a fixed position but they machine a bit off the bottom and then shim it up effectively giving you more lift. Not sure what gains you would see from this on a 4efe. Someone else may know more Quote Link to post Share on other sites
