I Have a used working Sniper 1 system with the full hyper spark for small block mopar i am about to list on hear. all you would need to make work is a fuel pump i keep my in tank pump Its on Facebook market place now. if anyone is interested asking $900 OBO as i am picking up a A833 today for the same price. was on my 82 D250 with a 72 360 got it tuned the best i could yes the self leaning is BS you have to use a PC to dial it in correctly. but after went i back to carbs found a intake leak and i have a miss match of cam timing and or torque converter stall to low i tried 3 different cfm carbs and only runs good with the 650 avs two. but half tempted to put the sniper back on if i cant sell after i go threw my motor and trans. i recommended you get your car runing well on carb first then do a efi swap

I have a Sniper on my 84' W150, 318 without timing control, I do have a ecu controlled distrubutor out of a '92 tbi 360, is there a way to make this work with the Sniper?

Hello, I'm looking to ditch the carb and run an efi. I would like to keep that carbureted look but that's not necessary. Now I have no clue what I should be looking for exactly but it is a 383 Big block in a 71' dodge charger 500. It has dual exhaust, 4 barrel carb, I bet there is more I need to list so let me know the information you need and I will get it to you or edit this post to include such, let me know what you guys think may be the best bet, thank you.

It all depends on what your looking for as far as performance?
I will tell you that you will most definitely need to upgrade your intake to a EFI friendly one. Yes a EFI will git most stock intakes but unless it’s built for the correct flow you’ll most likely get a rich condition. This is because the spray will bounce off the inside of the intake in a way that will turn the vapor into a liquid. Please don’t just take my word for it do the research.
If your looking for power and performance also look at headers and a 3” exhaust with a crossover X pipe.
Flow is the key here. Plenty of fuel in and plenty of exhaust out.
If your just looking at getting away from the carb and having an easy to start and tune engine Holly EFI has a great system. It’s all a money pit.
Your looking at modifying your fuel and exhaust and ignition system to get the most out of your engine.
Let us b know how you make out.

For me personally I wouldn’t get any TBI injections system don’t matter who makes it . Think about it like this
Carburetors were around beginning to the mid 80s .
TBI injection mid. 80s to end of 80s
MPI injections mid 80s to current

I would go right to the big gun and get. Holley terminator x and make the car MPI injection. Plenty of ppl can modify an Intake for injectors & rails or some company’s even make a efi version intakes now .
My car is on MPI and it’s light years ahead of any TBI units . Yea either conversion will cost you money but spend the money right the first time not the second time

Carbs have been around since cars were invented (Karl Benz invented them I believe).

Some good advice here overall. Having done 5 or 6 of these, here are my points;

1. Don't be afraid of doing it, not rocket science. Any EFI system will probably be beneficial over a carb unless you are really good at tuning the carb OR are running a full out race car (carb can be better at that to a degree)

2. Biggest mistakes made with EFI are typically bad wiring and not following the instructions. When it says the positive wires MUST go to the battery that is what they mean.

3. You need a good clean electrical system meaning you need to be running a decent size alternator and have good wiring. This doesn't mean you have to rewire the car but it does mean clean connections, good wires (not old and brittle), etc. The EFI system has to have clean consistent power, the ECUs do not like power spikes and drops.

4. You can make your own fuel system but you need to understand the EFI system requirements. You must have filters and a good pump AND a return line. There are many ways to accomplish all of this but if possible most just replace the tank with a setup from TANKS Inc.

Once you go EFI (assuming it done right) you will wonder how you ever used anything else. Good luck and have fun.
