Sniper Tuning

[elwaupo]

I have a Holley Sniper on my relatively stock SBC and sometimes when I step on the pedal it backfires(or something like that), any clue to what that is?

[SSLance]

Are you using the Sniper to control your ignition timing?

[elwaupo]

I’m using the large cap HEI distributer, i remember setting the timing when I installed it, I went just the basic setup. I’ve been thing of buying the Hyper Spark if that would help

[Tsaints1115]

Sounds like a timing issue. Any chance you're off a tooth on the cam?

[dontlifttoshift]

Backfires? Like out the exhaust?

Or does it sneeze through the throttle body?

What happens to AFR when you step on the gas and this happens?

[elwaupo]

Sneeze and I think the AFR drops a bit. It almost or sometimes dies so I keep my foot on the throttle to keep it from dying. I disconnected the battery and reinstalled the set up and took it for a test drive and it sneezed

[elwaupo]

Highly doubtful my timing chain would be off tooth, motor is low mile, I’m thinking it’s timing on the distributer

I accidentally installed the distributor 180* off in my 351W. It started but ran like s**t doing some things similar to what you describe. I realized my mistake and spun it around and it was golden.

Mine is non timing controlled
