So the plan is to run out of the box TFS heads on a standard bore 390 with a 4.25 stroke crank (438 cubes). Joe has a Victor EFI with the 4500 flange. From a simplicity standpoint (shipping, purchasing, etc.) would the Victor with the 4500 flange be suitable for an engine that size running 9.5 to 10.5(ish) CR?
Edit: I forgot to add I plan on using one of Holley's throttle bodies. The 4150 TBs are 950 or 1k cfm and the 4500 TBs are 1.44k or 2k (2k has progressive linkage) cfm.
