Re: Gen I 350 versus Gen III 5.3 weight
Yep...Though I would be interested to discover whether there is a difference in the spring rates or if it is a marketing thing. As well, I would like to see if the springs were different form the factory. I can tell you that I have not seen a build sheet with one or the other annotated but it would make for an interesting discovery. If there is a difference, GM may have included in the 396/400 engine upgrade. I'll call the GM dealer tomorrow to find out if there is a difference.
