Carburetor, MSD, Holley Sniper EFI questions

I have been go going to Holleys website for a couple of weeks now. Thats how these questions got into my head. I may have to actually give them a call. I just want my knowledge to be better so I don't get sold something I don't want or need. Buying their complete ignition system sounds like solid advice. I'm pretty sure whats under the hood now isn't made anymore.

I wrote a couple of articles on Sniper install that are on the Hot Rod website. I highly recommend buying the Holley Hyperspark distributor in addition to the Sniper. You can also buy the Hyperspark ignition box and coil or use a MSD box if you have one laying around. If you are buying new parts then just stick with Holley for everything including the fuel pump. Depending on which car you have you might be able to buy a drop in fuel pump from Holley that bolts into your existing tank. That is a really clean solution if it is available for your make and model.
