Computer and 305/350 swap?

I have a 1988 Iroc with the 305 TPI, auto, and 2.73 gear. I am replacing the 305 with a 350 with L98 heads and LT1 camshaft. My question is do I just change the MEMCAL or do I have to change the entire ECM. I plan on running the 22# injectors and have the motor mostly stock for now.

Thanks, Mike Jones
