Thread: Intoduction

Welcome to the site! Sounds like a nice Buick. There should be plenty of info here to top swap a Series III w/o blowing it up, lol.. Best way to search I've found is to use Google and type in what you're looking for, such as "top swap 2005 engine" and add grandprixforums.com behind it. The search feature here is kinda strange sometimes.

You might find an old HP Tuners around for it if you look. Not sure what else is out there right now.


Also, love the 04 Silverado. Hopefully that's the LM7 5.3L.
