Is this something I can do myself? I'm pretty handy I just want to make sure I don't mess this up! The motor is an 8BA and is assemble except for the intake.
I know drilling and tapping cast iron is not that difficult, but I'm open to suggestions.
Thanks, Joe


Joe sadly the builder should have had a clue on what to do since this is a common improvement to do when using the 8BA block especially when adding a blower or even any early multi carb intake. Drilling and tapping the holes is easy just take the time to tape up everything so no drilling and taping metal gets inside the valley intake ports or cylinders. The intake is your fixture to guide you on the hole center location you can also use a stock 1948 or earlier stock intake for the location points. Theres no issues with hitting water since no water passages are located in the areas you will be working on. Take your time keep the drill and tap straight and you will be fine.
