    Very slow Alpina 4,6l V8 swap

    Lets start with engine build.
    I was looking cheap replacement for S14B27 engine.
    So i bye Alpina F3 engine with head gasket failure.





    After disassemble, i look all the parts and think, maybe i do some tuning also before rebuilding it.

    Find some S62 parts:



    Also i take Alpina heads to flowbench.
    Heads flow 580hp/12mm valve lift (28")
    Now i know that heads are ok for better cams.
    After some search, i go with Schrick 292/284 profiles for S14 engine.

        I also cut 1mm from head to get comp ration to 11:1



        Alpina cams regrind to Schrick spec.


        I also go custom shim under buckets.





        Valve springs come from Ford modular 32v engine (eibach race parts)
        Upper retainers are from S62.
        Now my valve/cam setup can handle 8500rpm.
        Of course i use 7500rpm limit, i hope my std rods can take it.

                    We'll begin with the small town of General Tso's,
                    And move to the Orange chicken province.

                        Thats very common on early Alpina F2/F3 4,6 engines. Weak gasket.
                        Newer 4,6l engines use mls type gasket.

                          I assume those motors are bored a bit, so theres not a big cylinder gap which could contribute to the head gasket issue. Looks like it was occuring at the other cyls too.

                            I'm surprised they didn't use MLS gaskets from the start, BMW made the switch with m62's starting in 97. What year is that engine?
