Just installed the sniper kit on my '66 Bronco with a freshly built 302. All I can say is "buy it"! Fairly simply install, throttle response is night and day over my 4 barrel Holley carb, increased MPG with more HP and the self tuning is second to none. Holley hit a home run with this EFI package. Buy the adjustable secondary link kit otherwise all four barrels will kick in at low acceleration which is a bit aggressive when cruising.

Awesome Upgrade!
