I recently installed the sniper setup on my stock 71 duster 340 4 speed.
I also installed the returnless Holley fuel pump that fits in the tank and hyperspark distributor and module.
Also the progressive link.
I took my time soldered every wire connection and routed all the wires carefully to avoid any emt issues.
It fired right up and ran freaking awesome. it was learning and everything was going great.
Then a couple days later I had to use my headlights.
The alternator couldn’t keep up. It was dropping below 12 volts. I barely made it home.
I ended up installing a 130 amp one wire alternator.
Then she fired up and ran great at idle but as soon as I touched the throttle it would die. I quickly realized my tps crapped out. Maybe due to the alternator issue or just a crappy part who knows. I replaced the tps sensor and it has been running great ever since. I don’t drive it often but have probably put about 200 miles on it since the install. I do want to take it to a local tuner though and get it on the dyno.
Holleys customer service is excellent!!
I did have to deal with them about a metal chip issue that I posted about a little while back.
I was going to install a double pumper and MSD distributor and 6al box. Also a electric fuel pump. When I started adding up all the prices it didn’t seem like it was going to be much more money to go with the sniper. I guess it was a few dollars more but I am very happy with my decision to go with the Holley sniper!
