FWIW, while I was looking for a spring set for my 70 BB LS6, there was no distinguishing between the SB versus the BB. Maybe I didn't look hard enough. I guess the factory deemed the difference in weight negligeable for weight, warranty, etc. I would think the same for the 5.3...that the weight diff between the SB and the newer LS motors is not enough to be concerned about. Just my take on it.
