I am switching out my 750 vac carb on my motor and going with an injection system. Drivability and reliability is the focus. The motor is a 468 rect port BBC at 10.5:1.
Has anyone here switched out a carb and gone with a Holley Commander or Edelbrock efi system before in a boat? I am trying to decide if the direct port injection is needed or if a TBI system is plenty. Looking for 900cfm+. I know I will need return lines to the tanks so there will need to be dual fuel line valves to switch tanks for return and supply. I am really curious if someone who has done this can tell me the difference before and after. I have done this on my race boats from carbs to injection but those are mechanical and look no way similar to these systems.
