I would leave the F150 the 351 that came in it. The Lightning engines were only 245 hp and 345 tq stock. the Regular 351's IIRC are 235 hp not sure on the TQ. And the ZF5 is a piece of crap. They take no TQ. My friends 97 F250 w a 351 and a ZF5 has been apart twice in 100k. If you want a stick go w a Richmond TKO. as foe a ECM for a stick? Leave the MLPS in the netral position.
