MC-71 Posted February 17, 2022 Share Posted February 17, 2022 I’m thinking about making a switch to a EFI system. 350 SB 600 Carter 4 Barrel Proformer Intake Sq Bore. Might be off a little on the carb. I also want to use a OEM fuel tank. I’m willing to shell out over $400 for the new sending unit. Need recommendations. Thanks, Carl Quote Link to comment Share on other sites More sharing options...
Blackhawk Posted February 17, 2022 Share Posted February 17, 2022 What's your budget for the total package? Does it need to look like a carb? Are you going to do the wiring and plumbing? This is probably the easiest way to convert your stock tank to EFI: https://www.holley.com/products/fuel_systems/fuel_pumps_regulators_and_filters/fuel_pumps/muscle_car_efi_modules/parts/12-303 Quote Link to comment Share on other sites More sharing options...
MC-71 Posted February 17, 2022 Author Share Posted February 17, 2022 Yes on everything. That is the fuel sending unit I looked at. Quote Link to comment Share on other sites More sharing options...
jft69z Posted February 17, 2022 Share Posted February 17, 2022 Only problem with those type of pumps is the OEM tank has no internal baffling to keep the pickup submerged during cornering, stopping, etc. and only gets worse as the fuel level in the tank gets lower. EFI isn't like a carb that has a float bowl to use as a reservoir to keep the fuel flowing into the engine during those conditions.. Quote Link to comment Share on other sites More sharing options...
Scott S. Posted February 17, 2022 Share Posted February 17, 2022 Hey Carl, I've been thinking about the same thing. Anyone I've asked seem to lean towards the Holley "Sniper" set up. But as I'm using the same intake as you are, the MSD "Atomic 2" looks like the better fit. (linkages,controls,etc.) And they're made by the same parent company. As to the fuel system, Holley makes an "in tank" pump/sender unit. Remember, fuel injection requires about 55-60 psi to run, where carbs are only 5-7 psi. So you'll have to change all your fuel lines to rubber ones. Hope that helps, Scott. Quote Link to comment Share on other sites More sharing options...
