Is it a 5.3 or 4.8 If anyone can help me answer my question I would greatly appreciate it. I have what a guy sold me as a 5.3, but I am wanting to make double sure it is. (I bought it for dirt cheap) If anyone has some info on how to identify this motor I would appreciate it.

It sounds like you have the heads off if so stick a tape measure down the hole and if the piston is 3.66 inches down then you have a 5.3 if it only is 3.27 in the hole its a 4.8.
