Thanks,

Not that this answers your question but here it is
I was told that the actual cam specs (the profile the cam was ground to) changed several times during the life of the 914 but the part number never changed. The changes were for emissions compliance and earlier cams had a better performance profile than latter cams. I don't know any of this for fact and I have always placed cam choice in the hands of a professional I trusted. In the past that was Elgin cams but I would probably consult with Jake if I were building and engine today.

There is only one reason to keep the stock Cam in a motor. and that would be to stay in stock class in SCCA.

I think this would be a stupid desicion.

If you want to drive and enjoy the car and you are not racing it in sanctioned events then one of Raby's cams will fit your needs. Will run cooler make more power and probably get better MPG.

popcorn[1].gif well ...would you consider, in your recommendation, that a stock cam is stupid....wheather or not , this person intends to use the O.E.M. fuel injection setup.?..A camshaft with too much overlap,causes , pulsations, in the intake runners, which the intake AIR flapper (controlling fuel delivery) interpets as ...(need more fuel,need less fuel) as the pulsations bounce the flaper back and fourth.).this can be a serious problem at idle...Consider?.. popcorn[1].gif .

Call Jake up. He has a replacement for the stock cam that plays nice with the fuel injection and gives a bump in performance.

While I have no experience with Jake's cam, I can tell you that the WebCam replacement for the stock cam (not their stock regrind) is CRAP...... They say the little mod they made gives you more power and will run fine, but you have MAJOR idle emission problems and a huge flat spot off idle. Go with Jake, go stock, but avoid cams that they say will give your more power and work just like stock.
