It would be a lot cooler if Holley just offered this distributor with your choice of gears..I think you can use one of their RTR distributors or some other ones and still have idle spark control but I wasn't 100% sure of that.   This is my first go at a Holley system so I probably took the path of greatest resistance.As for fuel delivery the Sniper 2 does not contain its own fuel pressure regulator and it requires 58.5psi.    I used a GM regulator that's integrated into a filter and dead-headed that (single hose) to the TBI.   The filter itself I mounted directly to the hardlines for supply and return using 6AN fittings, and I made a small bracket to support it from one of the existing holes in the rear of the strut tower. It sits at a sort of silly angle back there because of how the hard lines come in but it takes up the least amount of space that way.   If I was really particular about appearance I would probably mount the filter/regulator in the back of the car and just run a single supply line.   Ford didn't do that with our cars originally because the fuel pressure across the injector was vacuum regulated so the regulator had to be in the engine bay, so the return had to be in the engine bay. The TBI uses a MAP sensor and constant fuel pressure so the regulator could be in back.  Mounting it up front here just means the fuel gets to go for a ride I guess.[ATTACH=full]50070[/ATTACH]It should probably be mentioned that if you live in a very hot climate or if you are running turbos or you're participating in racing events that last longer than 15 seconds you might want to use a return regulator instead of doing it deadhead like this because a return regulator that flows the fuel through the TBI will help cool the fuel at the injectors.    I do not anticipate this being a problem for me.</blockquote>
