My buddy just got him a 03 RST with a 4.8 auto in it. He wonders how it'll do against my 5.3. So we're comin back from town and hit a straight on 270 and both get on it. To my surprise he jumped me slightly and continues to slowly but surely pull away from me. He thinks his truck is stock but it don't hit the rev limit till 6200. I'm still confused on how he beat me. He may be 373 geared but would he really walk off like that? I got 342 and I hate them. I don't know how it happened but it did.
