  Dmoney74 & Shashi27 keep us posted how your Sniper setups go.  I have considered this setup. I would like to know the fitment of the Sniper distributor in relation to the back window and engine screen.  I would like to run my setup under a stock 74 engine screen. From what I have read many have more success with the Sniper FI if the full setup of Sniper distributor and ignition box is with it.

If you want to take full advantage of the Holley Sniper system, you can set it up to run a coil on plug ignition. You would have to install a cam position sensor, which will replace the distributor and eliminate any possible clearance issues that you would have with your engine cover screen. Of course, using a cam position sensor would require the uses of a crank position sensor, but it does make the set up almost like a modern car. I had no clearance issues with my engine cover screen when I used the FAST distributor on my EFI system. When I switched over to the FAST Dual Sync distributor, I had to trim on small piece of bracing on the engine cover screen to allow a couple of the spark plug wires to clear it, but the screen still fits. The installation of the FAST Dual Sync distributor allowed me to switch my system from a bank fired port injected EFI system to a sequential port EFI system. The sequential port system has been an improvement over the bank fired system. The engine runs smoother and my fuel mileage improved by about two miles per gallon.

Well. First lesson, if you are going to add a hyperspark distributor, do yourself a favor a figure out what metal you need to run on the distributor gear before you order the distributor. The gear in my car was bronze. Will save you time to ship the distributor back to Holley to exchange the gear, and $$ for the shipping. And the shipping is ridiculous. I can’t believe how expensive shipping is, even with USPS.

2nd lesson: if you're also thinking about a new steel roller cam, some U.S. cam grinders will replace their steel #1 cam journal & gear with a stock cast iron gear & #1 journal, keyed & pressed onto the steel cam. Then you can use a stock iron dizzy gear & no problems.  But you have to ask- the Cleveland is the only engine they do this for and the only one that needs it. Bullet Cams & I think Comp Cams.
