Valve train is about as light as can be , don,t know what else could be done ..  The intake closing I look as the best place to get ultimate charge .  The cam gear is adjustable , new gear with old center .

RE: bantam turbo - Colin Reed - 16-06-2020

HI STEVE,
What is the part number for the valves.

Cheers Colin

Steve, 
              your engine development work is superb. Can you please tell me what you did for valve guides, were they machined specifically for the job? 
  Best wishes, 
                          Robert.

The Ford valve stem is smaller , my machinist made a insert inside of Austin guide  .  There are different ways to do this ..  A good machinist can do this or make a one piece guide  ..   STEVE
                    This is flywheel notched 60 notches minus 2 for the Electromotive  ignition .. A magnetic pickup in the case sees the flywheel notches and when the 2 missing notches go by it tells the Engine Control Unit where the crank position is to fire spark plugs ..  The flywheel is not lightened to keep the spinning inertia going between shifts ..  Next is assembling rods and pistons and install of windage tray , oil pump with micron filter on pickup and block to crankcase re enforcing studs (2)  ..  Ali pan is on and 3/8" ARP studs in block with .044 thick solid  copper head gasket ..   STEVE
        The adjustable cam timing  gear ,  which is adjustable from where the generator mount was  ( there is no generator and the piece  that covers the cam gear is changed) , you will see that later .  The head is test fitted with ARP washers and 12 point nuts ..  Studs are sealed for water seepage and Loctite ..  The water circulation this year is  from a tank behind driver that will be pumped to the 2 fittings in the head  and to both ends of the block in the port area , (and to turbo for cooling ) then  out the side manifold back to tank .  Things will come together later as assembly goes on ..  STEVE
