Holley Sniper EFI After 3 Years - Reliability and Issues

Holley Sniper EFI After 3 Years - Reliability and Issues

[dalemccartney]

Thanks for posting this. I haven't seen many videos talking about these systems over the longer term. I'm having one installed in my car, though it's been in for almost 2 years, so I'm hoping to find out in the next couple months or so how well it performs on my own car. I'm having the Sniper 550-866K small bore unit installed to replace the Chrysler lean burn carb system.

You need to find a better ignition source for the pink wire. Mine did exactly the same thing until corrected.

Think u are right could also have lower fuel preasure due to dead battery too . I'd try starting it after it has like 12.5+ volts. U should get a battery tester to tell u how many amps the battery has. I use one everyday at work.

Nice car man!…shes cute!…and that 327 sounds awesome!…will be putting a Holley sniper on my Olds 307 that I rebuilt!

That heavy voltage draw in cranking could be from worn bushings and brushes in you're starter motor, never hurts to pop them apart an clean the armature and such. 25-30$ in small parts can often bring them back to life for another 50 years

3 years and only 2500 miles? "C'mon, Man', drive that

I have the MSD atomic system. If it sits for months it will start immediately then die. Will do it twice before it stays running. If I cycle the key 2 times letting it prime each time, it will stay running on the first try. A friend has the holley system and does same thing. Your fuel mileage improvement is because your carb was running richer than the sniper.

Cool car. I see you have the back up car mounted on the wall!😆

Some bounty sheets for mice control, nice!

60 year old wiring is always been the problem that I have seen. Was the holley system wired into factory wiring? With electric fuel pump, fans, fuel injection, the entire wiring needs to be modernized.

Can you share the spring brackets and throttle cable bracket model used in your project?

[DennisJohnsonJOHNSON]

Did you actually finish the manifold conversion?. I am doing the same thing but have found a spacer thickness of about thickness 3/4" i needed needed

[AuroraLowe-kp]

if you totally disconnect the sniper from the battery you clear the memory to the ECU requiring it to go throw the learning again, try driving awhile and let us know if it improves?

I see you have return springs on the throttle. Is that in addition to the spring on the EFI or did you remove the EFI springs and add your own. My Sniper has a very stiff spring and gas pedal as a result. Just wondering if you had that problem.

Amperage you wanted to say, not Voltage, upgrade the alternator . . .

Hahahaha! Where that FI startup reliability???? My carb would start easier than that on a cold Michigan night.
