Holley Sniper

[Green411]

Re using a Holley Hyperspark distributor: the Sniper 1 can drive the Hyperspark but I can't remember how easy the connections are. Or you can lock out the mechanical advance on the stock distributor and get the Sniper to run that. In both cases you tell it to run the distributor in the hand-held terminal's base settings menu.
Re throttle bracket geometry, Holley sell a small Mopar/Chrysler extension bracket, (Hly-20-7) which I used, to get the geometry right. Apparently Torqueflites use rods & bellcranks for managing the upshifts and kickdown and the added width of the Sniper vs a carb, plus a bit more still from the adaptor bracket meant that it seemed best to get a new top rod (the cranked one from the throttle bracket to the top bell-crank) made. This was a mirror image of the original ie the bend was in the opposite direction, but it was the same length & number of threads. It took a bit of internet research followed by a bit of playing about to get the adjustment right. Probably easier if you remember to count the visible threads on the stock setup first, which of course I forgot to do!....d'oh....

Here's a list of all the parts I used - hope it helps:
Holley: Sniper Classic gold (550-516), Drop-in Returnless Fuel Module with 255 lph pump and Hydra-mat (12-131), throttle lever extension for Chrysler (20-7);
