    may sound like a dumb question.... but...why? I have never timed it, but if it takes 20 secs to go 0-60 in my rig... i dont really care. lol!! K5s are pretty heavy... any engine that would really get-up-and-go is bound to have crappy mileage, and mine is already bad enuff thanks. /forums/images/graemlins/wink.gif

    Some of the guys run 14 seconds in top truck challenge with tires that big. Pretty much just cubic inches and gears for them.

    I know a guy who claims he can run 12's with 44's. He has a 502-- i think its blown, 14bff rear d60front, 4.88's or 5.13's, th400, np205, and 44" boggers.

    But if you just want decent acceleration a stock 350 with the right gears will let you get up and go with huge tires. Just get some 4.88 or 5.13 and it will help a bunch.

    I ran 4.10's and 44's for a while. I could smoke my buddy's k-10 while I was towing a utility trailer between stop lights of on the highway. One time, His truck broke down and I had to tow him home. He said we went faster up the hills than he could drive himself. That Goodwrench 350 crate motor speaks for itself! The Jimmy weighed in at 6975# full of fuel and my fat ass in it.

    I love my Goodwrench 350. Gotta be twice the power of the stock 305 it replaced. They must have better heads than the stock motors, but I've never found much good info.

    My truck is actually pretty quick. And off the line it jumps, that low first gear makes a big differrence!

    Here is something to think about.
    http://www.4lo.com/geartable.html
    Notice that to get "factory performance" you need 5.71 gears and 7.17 for better performance... That's 3559 rpms at 65 miles per hour, which is pretty steep, but it'll let a built SBC stand up and talk. Good luck getting axles to hold up though...

    If you want to ride in style and still give people a pause, consider a late model diesel. Imagine the look on their face when a big fat crew cab smokes their tail (literally, nice black smoke). My stock DMax in an '02 2500HD is (IIRC) 320 hp and 540 ft/lbs (rear wheel and below 3k rpms) and I can get close to 18 mpg if I drive easy. For $600-700 I can get a computer box that puts it up to around 410 hp and close to 700 ft/lbs (again IIRC, I don't follow this stuff to closely). The Dodge Cummins can go beyond that. Problem is, it's hard to keep a tranny (or anything else) together behind that much torque...

    That's why Diesel trucks should not be automatics.
