A buddy of mine has a shop and he will be doing a Magnuson on soon on a 5.3L. That would also work on yours over a turbo.

Jesus H. Christ, does anyone have a definitive answer on how to tell the difference between them, 821's came on trucks and vettes, so unless you go inside them, you wont know, and are there diff combustion chamber sizes on 821's as well because of the VVT and the CR's of Vettes as opposed to a truck?
