im thinking about changing my blazers tbi set up to a cpi. but im not sure if i go pull one off of an older blazer or 4.3 engine that it will fit or if it will be worth it. anyone have any opinions on this?

 

Are you talking about the vehicle noted in your signature or something different... I ask because a 2000 Blazer has the SCFI engine which is more reliable than the older CPI engine when it comes to the fuel injection system.

 

ya thats what i thought, but what about power wise?
