papasmurf Posted November 16, 2007 Report Share Posted November 16, 2007 So I just got a chance to look over the new engine I got for my Z. It's an l28 with an n42 head and the cam shaft is not stock. Yay maybe it's better maybe I scored big time well I don't know yet because I can't for the life of me figure out who made it and what it's specs are. So here are the clues I have gathered so far: has stamped on it between the lobes "D2" and "CWC" on the end what I can only assume is the grind number is "686". Google has turned up nothing, I posted on hybridz and have yet to recieve a good answer so I'm turning to you. Be my detectives crack the case guys. I wanna find out some specs and know wether or not I scored here and if it's worth using this cam over the stock. Quote Link to comment
hang_510 Posted November 16, 2007 Report Share Posted November 16, 2007 ive been looking into the same thing (for an L 4cyl cam) got measurements on the lobes and need something for angles to detemine the rest :mellow: so.... Quote Link to comment
521Lvr Posted November 16, 2007 Report Share Posted November 16, 2007 I believe that the "cwc" is a Schneider brand cam and might be a regrind and not a new cam. contact schneider and give them the #. they will give you the specs. if it is a regrind. you will have to. No Exceptions. use a degree wheel to install it correctly. Regrinds can be 10-12 degrees off from factory spec and sometimes {most of the time} need an adjustable cam sprocket to get the cam timing perfect. my personal experiances. peace tc Quote Link to comment
papasmurf Posted November 16, 2007 Author Report Share Posted November 16, 2007 it's not crane and it's not schneider Quote Link to comment
banzai510(hainz) Posted November 16, 2007 Report Share Posted November 16, 2007 I have a schneider and a Webcamshaft both have CWC on there so maybe is a Master casting from one company. Comp cams elgin Isky (dont think theres has a CWC but never seen a new one up close) sometimes its kinda hard to search their websites and figure this out I didnt know Elgin and Comp cams still made nissan camshfts myself. Most others are regrinds. who know????????? Basic is measure with a caliper the lobe then measure 90 deg to get lobe lift subtract the difference (be like .277 )then multiply by 1.48(1.5) .277x1.48=.409 valve lift. this would be close to stock specs duration ???youll need a degree wheel.
