What do you want to know about it ? It swaps out the same as the rest of the LS motors. Looking for size choices ?

Being A GM engine as said it is extremely similar to the rest of the gen 3 engines, same bore as the 4.8, same stroke as all the motors up to 6.2l, same intake and exhaust manifolds as a 4.8 and 6.0l engines of the same year. Information is pretty universal. If you want to know say head casting number it is plainly visible at the corner of the valvecover look for a 3-digit number like "706".


What do you want to accomplish with it?

Some popular cams for the 5.3 in the trucks are 212/218 and the 220/220.
