289 to 351 swap

[WVKICKSTAND]

THE 351W WILL FALL IN YOUR 68. IN 67 THE MUSTANGS ENGINE COMPARTMENT IS WIDER THAN 64-66 TO HANDLE THE BIG BLOCK FE MOTORS.THE ONLY PROBLEM MIGHT BE THE FLYWHEEL.THERE ARE 3 SIZES OF FLYWHEELS THAT I KNOW OF.ONE WAS USED FOR V8 MUSTANG II'S (WHICH IS THE SMALLIST)THE NEXT SIZE IS USUALLY FOUND IN CARS LIKE YOURS AND THE BIGGEST IS USUALLY FOUND IN BIGGER CARS AND TRUCKS.I THINK YOU CAN SWAP THE FLYWHEELS IF YOU NEED TO I THINK THEY ARE THE SAME BALANCE.SO IF YOUR CAR HAS A SMALL BELL C4 USE THE 289 FLYWHEEL IF IT HAS THE BIG BELL USE THE WINDSOR FLYWHEEL. YOULL BE ABLE TO TELL WHEN YOU PULL THE 289.IF YOUR USING STOCK MANIFOLDS THE EXHAUST WILL PROBABLY BOLT UP. IF NOT JUST THE DOWN PIPES WILL NEED TO BE LENGTHEND. THE ONLY OUTSIDE DIFFERANCE BETWEEN THE 289 AND THE WINDSOR IS HIGHT OF THE BLOCK WICH IN TURN ALSO MAKES IT WIDER.LET US KNOW IF YOU FIND SOMETHING IN THE SWAP IM NOT AWARE OF. I LIKE TO LEARN AS MUCH AS POSSIBLE ABOUT ALL FORDS!!!
