Grounding questions.

You are going to want a clean ground for your FI system. Ground noise can cause issues there.

Battery up front, ground using a good size cable to block if possible. The trans could use one as well... the starter bolts up there and NOT to the block. ever seen a fried/cooked speedo cable? Guess what caused that.

When the engine is painted, make sure the trans mating surface is clean, no paint.
