305 to 350 in 89 Bird
So,
I know this question has been asked a ton but have one un answered question. I have an 89 firebird formula with a 305 tbi auto. I purchased a fully dressed 350 tbi out of a mid 90s Silverado. Since the motor I purchased is complete, What would be the process of swapping them? Fuel pump and ecm? Any help is greatly appreciated.

Get a 350 chip or a custom chip burned for the car ecm.350 ESC module. Use the 350 throttle body, use the 350 knock sensor. Pretty much a Simple swap.
