In case some of you do not know here is a link to my 8-71 EFI project for my BBC Jet Boat.
Anyway I was able to get the fuel rails machined (not on my lathe, too small) on my Father in-laws buddy lathe a while ago. I brought my -10AN O-ring tool with me a did it there.
Fast forward to today. I had to make stand-offs for the fuel rail to the injector plate. Took some measurements and milled away. The bolt that holds the stand offs to the plate is counter bored. Tomorrow I will finish drilling and tapping into the injector plate and also in the fuel rails where the stand-offs will mount. Pics.
As you can see in the last 2 pics the valve covers hit the Dyers manifold. I know I can put a nice radius on the manifold but my options are open to new valve covers as well.
