Considering Holley sniper EFI for my 1969 340. Thoughts from people who have that set up?
One more recommendation - given the chance to start a new system again, I would use the new Holley Power distribution block.
It would make installation a lot cleaner and eliminate the usual problems that a lot of people have.

Apparently it also works on Sniper 1.
