Head swapping in my 1993 F 150 4x4 302 EFI MOTOR.
FIRST IS THE DISTRIBUTOR SHAFT ON A 351W LONGER THAN
THE ONE IN A 302 BOTH MOTORS ARE EFI 'S. THE 302 IS 1993 /
351W IS 92.
THIS IS WHAT I NEED TO KNOW , WILL THE HEAD OFF THE 351W
MOTOR FIT ON THE 302 ? THE 351 BAD BOTTOM END, 302 HAS
WHAT MAY BE A BAD HEAD POPS OUT THE EXHAUST AT A IDLE
AND RUNS LIKE IT HAS A DEAD CYLINDER UNTIL IT WARN UP
THEN SOME OF THAT GOES AWAY
