I am happy with the system overall. There are a couple things I would change in the design but very minor things. They have not put carburetors on a built from the factory car in about 20 years for a reason. I personally would never ever purchase another carb again and I strongly encourage my friends not to use carbs. The more complicated installation if you want to call it that for EFI gives such a better running result. No adjustments required and the self learning makes it the ideal setup compared to constantly fiddling with a carb.
You happy with the system.. I just bought this today because I just installed sniper efi and I got 1 mile down the road and blew another hei module.. I am tried dealing with the old hei I hope this fixes my ignition issues.
What fuel pump system are you running. I have a 1969 RS/SS convertible that I'm installing the sniper system in . Holley hyperspark dis and CD box and coil. I purchased the new retro in tank efi in tank pump that Holley is selling and they state that with this in tank system, you do not need to run a return line for the fuel . Just FYI for anyone thinking of installing a EFI system.
Having dealt with the in tank system it only fails when your tank is full.. But I do not trust the no return in tank design as it can cause issues with continuous flow and pump never shutting off. I did inline easy to get to easy to replace should it fail. If you order the sniper inline you get the Walbro GSL392-400-939 255 lph pump. It's been in two years and has not failed so I'm very happy overall. Just be sure to use a 100 micron filter before the pump and a 10 micron filter after the pump. Put these in easy to get to places also.
I used to r & r Chevy V8 distributors a lot back in the day when I was swapping a lot of intakes and such, and found that if the oil pump shaft is a little off all you need to do is get the gear teeth engaged and go briskly up & down with the distributor, and every time the distributor shaft bumps the oil pump shaft it rotates it slightly because of the helical gear rotation, 10 or 12 quick bumps and the pump shaft comes around, then it drops right in the slot. Even if you have to go 20 or 30 bumps it's easier than cranking the engine. I have a '68 Camaro too and I want to do a 383 SB with the Holley setup just like this and mine will also have PS and A/C, I like the looks of that accessory drive, did you get that with the engine from Blueprint?
@@Icecobra47 I thank you. I've got an xFlow on the way and was looking at the different installation methods. Unfortunately, I'm pretty sure the xFlow is going to need an external regulator. I really like what you've done. You've given me some great ideas. Thanks!
It's arguably the best system for carb replacement/look alike on the market. There are better systems with direct injection and after it's all said and done, they are more expensive but you get more performance/better results. One huge pro to the sniper set up, as long as you're with in the HP range, is not having to change injector sizes if you put in a bigger cam or different heads etc. It will tune its self and has a lot of head room. Great setup for older stock motors too with the 2 barrel rochester, Quadrajet, and single barrel (ford inline 6 I believe). Most cases get the master set and few hours down the road.
Nice clean install and gorgeous car! I installed the Sniper and I'm thrilled with it as well. I hesitate to use the distributor because I use a vac. adv. and my car would be a dog without it. Wondering if your car also had vac. adv. and if there's something built into the snipers timing control that mimicks vac adv?
The sniper uses internal programming to advance timing. As rpm increases the timing increases. You set parameters in the hand held to determine the advance. On mine one setting is max total advance I set to 34 degrees. By setting the timing at initial setup the system advances timing accordingly.
@@Icecobra47 Thanks for taking the time to answer me Richard. Can you set it up so the advance is responsive to vacuum or is it just a set curve? Thanks again. Scott
@@ScottDLR Hi Not sure why you would want the advance tied to vac. The way Holley does it is tied to rpm of course as the RPM rises your timing advances. It really seems to be more of an accurate way to do it. Vacuum can be a variable especially with more cam your vac becomes more erratic and less of a guarantee. I am fairly certain it is a curve in part like a vac curve. The critical part is telling the system what the timing is so it can do its thing. I did order the link cable to tie it to my laptop once I hook that up I can probably have more control of timing mapping but I will know more when I get the cable...
@@Icecobra47 The only reason is because my eng can take a lot more advance at light throttle (vac. high) than it can under heavy load (vac low). That's where the vac. advance shines. I suspect there's some way to achieve the same thing electronically though. Maybe I'll give Holley a call. Cheers, Scott
I’m getting ready to do this swap on my 86k10 . Did you have to change the sending unit ? I’m confused on how to run my plumbing A. Cause I have dual tanks and B.cause I’m unsure if I have to change my sending units or if there’s a sump I can run externally.
Well with dual tanks you need to put the fuel pump after the tank switch. Im not sure about the in tank fuel sending units or if they are the fuel pumps on your model bypassing may be necessary.
This is a multi piece setup you order each item separately distributor then coil pack and capacitive discharge box. It's a pretty easy plug and play system.

NIce car, you do good work!
You happy with the system.. I just bought this today because I just installed sniper efi and I got 1 mile down the road and blew another hei module.. I am tried dealing with the old hei I hope this fixes my ignition issues.
Can this distributor be installed with just the Distributor alone and no Ignition and Coil box?

Nicely done. I really like the way your routed your fuel lines. Where did you put your regulator?
Regulator is built in to the holley all you have is feed and return
@@Icecobra47 I thank you. I've got an xFlow on the way and was looking at the different installation methods. Unfortunately, I'm pretty sure the xFlow is going to need an external regulator. I really like what you've done. You've given me some great ideas. Thanks!
I am contemplating running the entire sniper system efi and ignition do you still recommend it? Have you had any issues?
Still a good system and I'm happy with it..

U can not run vacuum advance with the sniper u have to lock out the distributor if using an HEI
Where did you get your cable cover set
I’m getting ready to do this swap on my 86k10 . Did you have to change the sending unit ? I’m confused on how to run my plumbing A. Cause I have dual tanks and B.cause I’m unsure if I have to change my sending units or if there’s a sump I can run externally.
Well with dual tanks you need to put the fuel pump after the tank switch. Im not sure about the in tank fuel sending units or if they are the fuel pumps on your model bypassing may be necessary.
Does the system give you an option to program in a vacuum advance setting? Any issues so far? Thanks!
It does give you the ability to dial in the advance and set the parameters. So far so happy with it I did the same to my big block chrysler...
I just finished up my 350 with same set up. How do you like it so far? Weather here in missouri sucks right now, not able to drive it.
its called detonation
Did the ignition box and coil come with the kit? Thanks
This is a multi piece setup you order each item separately distributor then coil pack and capacitive discharge box. It's a pretty easy plug and play system.
@@Icecobra47 Are you happy with the performance?
@@russelltimmins3490 I am completely satisfied with it and the car has never run better
@@Icecobra47 Great thanks. I think I will splash out and order it.
