I'm glad this topic is back up. We're going with the Holley super sniper stealth 1250 in the next few weeks on my 70 GTO with the 468. I was concerned about the 72* of overlap and low vacuum, but shop has assured me that is not an issue., but what happens when opening up the dumps that is about 18" from the AFR sensors? Any questions or concerns I should be aware of?

No problems with that. We are running a pair of Super Sniper Stealth 8 injector units on both cars. I have cutouts on both cars about 18" behind the 02 on one car and 22" on the other. That's just how it worked out with the room I had.

Only thing you'll notice is the AFR immediately starts correcting the fuel table as soon as you open them up, which is what it should be doing.

Low vacuum isn't an issue either. Both cars only make about 6-7 inches at idle and the Snipers work fine.

Great, and thanks.
