Kinjo, my heavy as hell 92 extended cab runs 9.51 in the eight and with the 1.56 factor to calculate the 1/4 shows 14.83 but I bet it runs quicker than that. My engine is all stock LS1 parts at this time. The truck even has heavy cast aluminum Eagle wheels with 32x10.5x15 tires, also heavy. The heavy tonneau cover and subwoofer box with 2 10" Stillwaters is a good 60 lbs more. How much heavier is an extended cab anyway? About 300 lbs?

My ext cab is hitting 15.4 @ 87mph with just 2.5" pipes after the header to a single in/out magnaflow with a turndown after that, and a k-n cone with the stock intake tube. I can usually take any singlecab that stock, I dont have a posi, and im still with the stock 3.42s and tires so i dont have an advantage. Its weird cuz i hear of trucks that have all this stuff and they are just hitting like low 15s, but i recently found out the reason, its all about location
i've ran mid 13's in my Ext Cab...with just a few bolt-ons!!!!
Hey Squirrel yea 13's with some junk on the floorI have never had an ext cab pull on me, but have had some stay right with me. My newest time in the 8 is a 9.29 with a sucky 2.63 60' (damn the TQ management) with the mods listed below in 39* weather

that was running a 125 shot. A lot of jaws dropped when i walked on a lightning at the track, after that none of the trucks out there would race me. They were being douche bags...making me line up against 9-10 sec outlaw cars.Originally posted by 2ktukin20s@Dec 11 2004, 03:59 PM

so you went to 4.10 gears, ported TB, and a better cam and you run the same?
only 100 bucks involved in the mods. the cam was given to me. so 3 tenths isn't that bad. i am still on street tires and spinning bad out of the hole.

I turned a 14.76@90.56 in my half ton crew cab, with a 2.124 60' time with just boltons, no header or cam yet.
