Dad has 4.10's in his vette, had them installed shortly after he got his longtubes + tune on there, and my god, those 4.10's woke that bad boy up BIG TIME, i tell ya, gears make a huge difference in terms of a cars performance.
He needs to stop stalling and get that thing in there for that procharger he's been babbling about for the last 5-6 months....
