Just curious if anyone is running an EFI system on a big block and how it is working out. I have been looking at the Holley sniper for my 440 and am very interested if anyone has tried it. It sounds pretty simple to install and use but I would like to hear from someone that is actually using it.

 

I have been looking at it also, the guys at hotrod put one on a sbf in two hours.
There are plenty of videos out on the net just google " holley sniper " for a grand I think it's a good deal.

 

Moving the threads along. Don't want this one to die off. I called fast and they said that if you're engine didn't pull 10hg vacuum you were done. So then I called Holley and they said that's not a big issue with their sniper system. So to me it sounds good enough for me to try it in the future. Only real draw back I see so far is the master kit can't be ordered with larger fuel lines or steel braided.

 

Look at the FI Tech System.... I know of three in just the past few weeks that have been installed and the guys are really loving them.... One is on a mild Big block Brand-X. And the other on is on a 408 in a Duster. and the last one is on a Stroker other Brand-X.... All of these guys are happy...

 

The only thing that's got me worried is the first start up. I would love to see a video of a 500 HP motor on first start up and what is needed to make her run right. I watched a 2 hr video of a bronco swapping one in and when they fired it up it sat at 4k instead of idle. But another video it seems fine on first start up. So where's the videos of over .500 lift at. Ha ha

 

Your going to need something more race friendly, 700 hp range.
I went carb Holley 950 XP, great carb!
