Technical Old school Mallory small block Chevy machined down to fit a flathead dimensions tech

I’m looking to machine an old Mallory sbc to fit a late 8cm block. I was wondering if anyone had the dimensions for the housing or what needs to be done. I know it’s been done before so anybody make a blueprint or jot down some specs. I’m looking to machine a few up one for a buddy and one for my project thanks

 

Here you go John, I don’t know how to post a link using my iPhone, but here’s the search I used to find what is in this photo-
machine a SBC distributor to fit an 8ba engine
That led me to this, and there is a complete description of the necessary steps.

 

@Fordors thanks for the link and lots of info on the site. Seems like a easy enough task to machine one down and just have to figure out advance on it…
