You can double check but I am fairly certain the 1969 and 1970 engine codes for 351 CID motors are the following:
H: 2-barrel 351W for both 1969 and 1970 Mustangs
M: 4-barrel 351W for 1969 Mustangs, and 4-barrel 351C for 1970 Mustangs.
Seems odd, in 1970 Ford installed a 351W when it was a 2-barrel motor and the 351C when it was a 4-barrel motor. You'd think for 1970 the 2-barrel version would have also been a Cleveland motor.
