Replacement engine
Will a 5.3 from a '99 Silverado be a direct replacement for a 5.3 in a '01 silverado without changing any sensors, connectors, or accessories, etc.?
Re: Replacement engine
you should check with a local wrecking yard to see if it's fully interchangeable. Napa shows the same long block for both years but Chev shows the 99 short block but a different number for the 2001 and it says the 2001 is discontinued. But I have seen the OE sites make mistakes before.
