Picked up an engine yesturday that is supposed to be a 5.3 LSx engine. Is there any easy way to tell the 5.3 from the 4.8? Since they use the same block and heads there is no give away there. Took it in trade for some other parts. Just trying to decide if I should put it in my car or sell it off. Thanks, Chris

I couldn't take the suspense any longer. I pulled the pan to check the crank part number. It is a 5.3. It is definantly going in the car. :happy:
