I am also thinking about going to a Sniper fuel injection setup.


I put the basic Sniiper system on my 440 based 511 stroker. I also used the HyperSpark distributor and the HyperSpark CDI box. I have to say it was a steep learning curve. The supposed "self learning" only adjusts the fuel table to meet the air fuel table that you create. The spark advance table that the Holley wizard creates isn't good. The Holley Sniper forum is a good place to go to get some advice on setting it up. I have the car running pretty good now, but it took a while to get it there.
In retrospect, I would go with the higher end Terminator Stealth series. It has more tuning capabilities. The Sniper 2 is not mature yet.

Just my 2 cents.

74 Challenger, bought it new. In 1978 I replaced the original 318 with a 446 and 727. Mild cam, Jardine headers, and Holley Sniper EFI.
New engine! 511" RB, Edelbrock Performer RPM heads, Eagle rotating assy, Comp hyd roller cam, Doug's 2" headers.
