We are now in full production of the EFI 97 These are our EFI throttle bodies designed to look like a Stromberg 97 ! These units are CNC machined, feature a single oval butterfly for increased CFM. We tested these units against an original Stromberg 97 and the results were incredible. We flow tested them on a Super Flow SF 600 flow bench. the Strombergs flowed 203 cfm and our EFI 97 flowed 344 cfm !!!! They feature roller bearing shafts, internal clock springs so there is no need for external return springs.
We sell these units as a complete kit with an Accel/DFI engine management system and a custom Autotrend EFI Harness You can see more detailed pictures here. You can also see them in action on a Blown Ford Flathead on the engine dyno by clicking here
