This is the 351 Windsor version of Pro-Flo 4, finished in black plasma rather than satin. Each cylinder gets its own injector on manifold-mounted rails, which is what gives the cold-start manners and part-throttle behavior a carburetor cannot match. It runs pre-loaded calibrations and self-learns as the car is driven, so a dyno session is optional rather than mandatory.
