Just finished the install of a Holley Sniper EFI on my 58, 3100, 235. This is my first experience installing an EFI system so I’m learning as I go.

I did have to get an adapter made to allow the TB to bolt up to the manifold.

After initial start up, the throttle blade had to be adjusted and it was ready to go. I also had to increase the start fuel percentage, which was done using the touch screen programmer.

Throttle response and starting have been improved. I’ve only driven it about 10 miles so far so I don’t have any fuel mileage numbers yet.

It’s been a fun project.
