  Hi,
  Did you use an Edelbrock performance intake or did you change to a
  Holley?
  Cheers
  Henrik

  We  just installed a Holley Sniper on a friends 1956 Chevy Hot Rod
  Pickup with a 383 ci. small block with a 700r4 overdrive automatic
  transmission,two weeks ago.
  We went with the whole conversion.The Sniper injection,fuel system and
  holley sniper distributor so we could control the timing with the
  sniper computer.It took two days to install as we did a few things
  differently than what came in the kit.
  He previously had an Edelbrock 600 cfm carburetor and a chevy HEI
  distributor.
  So far it is working amazingly well.He says if he didn't know better,
  we changed his the engine in his truck to a larger one.It has
  significantly more power and runs smoother.Much better cold
  drive-ability,and part throttle response.
  I believe most of the improvement was because his old distributor did
  not have the correct timing curve and the carburetor was too small.
  There are a few things we did differently versus what the instructions
  say.We welded in an oxygen sensor bung versus the drilled and clamped
  on bung that comes with the sniper.We also used 3/8 copper-nickle
  tubing for most of the fuel system versus the push-lok rubber hose that
  comes with the sniper.I only used the push-lok hose in a few places for
  vibration or movement.I used it at the throttle body ,between the fuel
  tank and fuel pump and filters.
  There are a few things to know when doing the Sniper conversion.There
  is a lot more wiring than it looks like in the sales pictures.A lot of
  it is not used as it is a universal system so it has wiring for several
  different ignition types.Most injection systems DO NOT like magnetic
  pickup distributors.That is one of the reasons we got the Holley sniper
  distributor as it is a Hall effect,and it plugs right in.We also
  shielded the trigger wire, as on the chevy engines the distributor is
  at the rear,which is also where the wiring comes out of the throttle
  body and we did not want any problems.
  Also inspect everything when you first receive it before starting the
  conversion.We did not receive the clear distributor rotor cover used
  when locking the timing.A quick phone call to Summit Racing where we
  purchased the Sniper got a new sent to us in less than a week.
  It went so well installing the sniper on his truck i plan on installing
  the same Sniper system on a few of my cars,including my Pantera which
  has a 650 hp 427 stroker in it.
