Hey all....Would like to trade tired 305 4 bbl. for 350. I'll be using Edelbrock cam to mimic 305 valve timing, and Edelbrock EGR intake with original Rochester comp-controlled carb. Will the extra displacement overwhelm the current computer programming? Any pearls of wisdom will be appreciated!!

 

What year is it? You will probably (depending on the year (pre/post96) have to have it modified for the extra cfm from the carb.

 

It's a 1987.

 

It won't have an ecm, (computer) if the car is an 87, therefore it won't matter as long as the cfm (intake/carb) is for a 350

 

If you are refering to an ESC electronic spark control, there will be some minor electrical issues

 

There's definitely an ECM tucked behind the passenger kick panel.
