    Make your own carb to TBI adapter

    Make your own carb to tbi adapter for an inline 6. Use your gaskets as the templates. The upper and lower plates are 3/8" thick. The side pieces are 1/8" thick. cut a 1 3/4" pipe at 172 degrees, 1 7/8" long and then split the pipe and flip one side and you have the 2 sides, cut the triangle pieces to fill in the voids. It ends up at 2 1/4" tall. Thread the upper plate for the tbi unit. I used my drill press to keep my tap square to the plate. I used a regular 1 3/4" hole saw at slow speed with plenty of cutting fluid to cut the holes. Hope this helps.
