    Febi Cam opinions?

    Im rebuilding my head and the cost of having my stock ones refurbed and a new Febi one is about the same. Are Febi stock replacement cams decent?

    Febi replacement cams are great. I've used them in 10 or so spec e30 builds with great results and zero issues.

      If you building a turbo engine and getting a new why not get a regind from Bimemrheads ? Almost the same price too.

        How is this an opinion on the Febi cam? (no offence to bimmerheads, but that's not what the op is asking).



        I've sold probably 20 or so in the last couple years. Had 2-ish that were verified too far out of spec. So the odds that you'll be fine are heavily in your favor (shoot there have been a couple oem cams outside the tolerance range).

          ive had 2 out of 3 catcams way out of spec so make of that what you want

          what particular specs are you referring to?

            Thanks for all the input! I am not adverse to an aftermarket cam, I just don't want to run the risk of piston / valve contact. I have a resurfaced (not shaved) head with oringed block and goetze head gasket. I have heard of some (rare) cases of even a 272 cam pushing a valve into a piston. Thoughts?

              Resurfacing a head is done by removing material. So is 'shaving', although i guess you
              might get less stubble with a shave.

              But no matter, if you're concerned, just use some modelling clay on the piston domes,
              then pre- assemble, roll it over and measure how thin the modelling clay got squished.
              If it's less than .080 or so, then it might be worth getting a little nervous.

                  Ya, I meant it was "only resurfacing" not decking or shaving the head to raise compression.

                  Does anyone have experience with the IE 272? I'm searching for thread reviews but can't locate anything :/ It seems like a great value, I just don't want to buy garbage.

                    IE 272 billet cams are very nice for the money. We've sold quite a few.

                      Can I do the clay spacing test on another bottom end, since the bottom end I will be using is still being used in my car?

                        No, you would want to clay your block with your head just as it would be finally assembled. We're talking about clearances of less that .100" That's why you've read about some people having P/V contact while others are completely fine.

                        There is a method for testing clearance with the head on where you remove the valve spring and drop the valve onto the piston at TDC, but I imagine it's harder to measure accurately.
