That Alignment is what I meant by Hall sensor L bracket and your engine plate pushing all that out 3/16 etc.
Because the IW bracket to block is flat, it might be easier to trim the 3/16 (whatever size engine plate is) off that vs the L bracket since it looks like the L is grooved like how we did mine.
I'm using an electric vacuum pump, which is the oddball in the world of vacuum pumps since most people assume it's pulley driven, which is what I bet Chris @ Torqstorm is thinking.
I'm gonna pull a good 10" of vacuum on the crankcase through the PCV hole and that will definitely help a Pontiac from blowing out the rear main seal under boost and making some extra power, 2%, while you're at it.
