Well.. My friend is about to pruchase a 1989 GTA bird that claimed to have 5.7L engine in it. We want to make sure that it is a 5.7L not 5.0L. Is there is a easy way be visually tell the different?? Injector colors, Block Codes and Eprom numbers etc.. anything well help. I need this info before 4PM PST.

Thanks in Advance.

 

run the rpo codes o nthe rpo decoder here, but that doesn't mean the engines not been swapped. can look up the engine code stamped o nthe block
