Considering Holley sniper EFI for my 1969 340. Thoughts from people who have that set up?

I have the older Sniper 1 system. I've had it on my 408 for a few years. I ran it with a points ignition for awhile, then ran it with a stock electronic ignition and finally upgraded to the hyperspark distributor. I used the Holley in tank sending unit replacement. I plumbed the fuel pump to the factory 5/16 hardline. The in tank pump also has a built in regulator so no return line is necessary.

Being able to change idle RPM, base timing, timing curves, rev limiter, launch RPM, electric fan on/off, etc from the driver seat is pretty nice. I plan on adding nitrous eventually and the sniper 1 has an option for that. I think you lose some input/outputs on the sniper 2, I could be wrong on that.

I have no regrets and I don't plan on ever going back to a carb. I'm currently swapping a 440 into my '69 D100 and have a carb. I'm fighting the urge to switch to a sniper on it also.
