 Aughh,  I understand now JB, that why BDA mentioned their brittleness .
 I questioned the two small holes below the adjustment screws being sealed off. I still have some disassembly to do but I’ll wait for the parts to come in, hopefully it will have some detailed instructions.
   I’m copying a friends car in a way but he recommended a 45 DOCE. I have yet to find his valve cover.
He also helped explain the water line cuts necessary.

Just be slightly wary of jet sizes as stamped on them, as it's not uncommon for engine tuners/dyno operators to drill out jets to suit and also to re-solder and re-drill. Always best to check with gauges if you can.

 Broadside,
 Thanks your statement is echoed in many tutorials I have watched .
  BDA
  You are correct the plate is now the same for old and new type 40 DOCE carbs . See pic

 Finished up polishing the intake manifold and getting the fit right inside the header plate . This will be the third time posting this with some tutorials, service manuals and tuning guide , so please excuse this shortened post. Please read the tutorial I post next , as a novice, expert or racing enthusiasts it has everything for all .

Pierce Manifolds is a good source of parts.

  Switching gears here a bit and decided to copy the layout and routing of the wedge engine headers  to the crossflow engine. Having the head plate all ready cut I opened the box of pipes and started slicing and dicing.  Going quite well I decided to post some pics . A lot of welding to do tomorrow but it is nice to have a plan for future upgrades.

   Finished the head plate  but still playing around with the 843 crossflow oval to round transitions . For the head to pipe the 1 1/2 “ round also need to be stretched to maintain dimension smoother.
Profiles all cut !😀.  Time to weld up!  I’ll just practice a little more 😂😂😂 with different setups
To produce the cleanest, strongest weld.

  Twenty different directions, a much needed wash to rid the body from aluminum and fiberglass dust before the granddaughter started to draw smiley faces on it.
 Crashpad coming out nicely and see a easy duplication process.
    Another mod is my alternator bracket to accommodate a SBC 100 amp alternator from a block of aluminum

   Found an interesting point on lotus talk about the forward bonnet catch assembly leaking water into cabin area over heater assembly.
   NOT GOOD!  I’m going to run an electric demister so I modified the catch . Wish I had a CNC , but chisels and files worked on a block of aluminum. Notched out and countersunk threaded screws, topped off with a nice gasket under the plate.
 Hopefully that will end that.
   My block of aluminum for alternator still on the sidelines until the new alternator arrives.  This will also allow me to transfer it over to a crossflow and block off the water passage.

I though I was the only chisel and file machinist here! I have to say you are a lot more adventurous than I am!! Please be sure to post what you do to that block of aluminum!!

  Absolutely BDA,
  I was going to send the plans to Chuck Nukem since I believe he has a CNC machine.  Not sure how many people would like a 110 amp SBC single wire alternator on their crossflow or wedge.
  It will look more like a block but all ready it’s lighter.
