ah yes...the ol' 120 engle cam..... must consider that when this cam was designed /it has been over 40 years ago/ 40X35 heads were in fashion and could only flow so much and the 120 was the answer to both worlds of the spectrum being that the 100/110 cams were widely used but were limited for more power...(fyi)the 110 was considered a 3/4 race cam..which made the 120 a full on race cam at the time... being that the duration was sufficiant with the 120 around the low 290's ... enough to make power down low still providing gobs of mid and top end charge for off roaders as well as two lane blacktop racers alike it solidified its placement and the vw ranks and led the battle to the 130/140/160 series cams and beyond. every engine "guru" has his or hers favorite cam but from my experience this cam brought forth the best of both worlds in the vw community. for years engle has played with valvetrain dynamics and longevity especially with vw's making them the number 1 choice for vw engine building to this day. remember>cam selection has EVERYTHING to do with total driveability..!! ...weight of car/tire selection/compression/carburation/displacement..etc...all have an important factor in selecting the proper cam. i ran the engle 120 in many of my projects as well as my (legendary)/1600 single port engine(early/mid 70's) ,which everyone said couldnt be done, and had xlnt results..achieving 15:01 with a sled notchback with street tires/fan belt/radials/and bested 41.6 MPG..!! >but mind you i researched many things to take into the equation for the results to become what they were. overall the engle 120 cam has solidified its existense and will continue for many years to come no doubt. as for "the mechanic's fondness" or dislike...he is absolutely right...when rebuliding vw stock or very mild applications ..stock cam of course...or an engle 100 can be warranted but to a true and dedicated engine builder of stock vw engines anything other is considered overkill... and for all the right reasons..!!

i never used it and i have always heard from one enginebuilder it isn't a cam that is very 'usefull'. so he never uses it, and i accepted that as being true as there are cams that seem not to be as 'hot/good' as others.
but indeed Mark H. liked it, and looking at the video it DOES perform really, REALLY good and now i read that others like it as much.
so enlighten me and show me the way to use a W120 in a way it should/could be used.
in a way i was thinking the W120 is the big brother off the W110 and therefore intended for 2l+ engines and the W110 is for sub 2l engines... ???
I re-read your post Nicolas,
The W120 isn't very useful?
I have to disagree.
I think any cam that can widen the power band of such a wide array of engines (cc wise, intake wise, etc) and STILL not beat the valvetrain into submission (provided it's set up correctly) could be deemed "useful".
I look at it like this: you can drop the 120 in just about anything and it will be "good" at something. It would be hard to go wrong.
Try that with FK87 or VZ35 or some other romper-stompy cam profile. If you don't get some "variable" just right on, you'll have a mess.
I wish the cam companies would give customers more insight instead of "Hot Street" or "Drag Racing Only"
you can take the 120 "Off Road" in the right motor.
you can drive the FK10 on other streets than the 1/4 mile.

The 11 year answer.
But I still liked reading the whole thread anyway.
