And the two different 351 configurations too - 351 Windsor and 351 Cleveland...
2 of my boys share a 72 grand Torino (same year as the movie of the same name). They have a 351 Windsor bored/stroked to 427 that was not the original engine. And the original Cleveland which is back in it and is closer to stock. They have throttle body FI replacing the carb on a four bbl manifold tied into the ignition (a kit including FI, distributor and an O2 sensor tied to a computer). It makes the engine run perfect at all speeds and loads. it cranks well for a 351
