for a 4.8L, 308 gears in a truck is a long time to wait, plus this truck shifts out at 5700rpms, no cam.Quote:

The truck in my avatar had 37" tires with 3.73 for a while. What a turd, but I could also haul on the freeway in 2nd. Overdrive was useless unless going down hill.
Are you sure? My 3.73s and 6200 was 90ishQuote:

Get your bottle pressure north of 950, that will help. Look in the glove box and get the RPO codes for the rear end. There is a list on here that will tell you what ratio is in it. I'm guessing 3.23's, if stock.
my 08' 4.8 came with 3.23s stock and could hit 105 in 2nd lmao effin slow..jumped to 456s and damm!

there was a truck in here the other day, had 4.56's, about a 30" tall tire, slammed, ran really nice on the highway. i'd say about 65mph around 2400rpms.
