Recent Holley Sniper EFI installed
I recently installed a Sniper EFI (2bbl) in my 78 J10 360.
Very happy with the performance afterwards. Smooth acceleration, no more cold start. Easy initial programing with included touchscreen. Touchscreen display stays connected and is a nice engine monitor (RPM, AF ratio, Temp, etc). Acts more like a modern engine now.
Easy install, took about 3 hours working slowly. Electric fuel pump install took more time than half the EFI install time.
Price was around $1,200 total including electric fuel pump.
