Oh yeah, that thing is movin' out.  I hope I can get my truck to run like that one day.  It would surely turn some heads.  You(LEPRCON) and Lorne got some fast trucks.

i don't know---i just had a hankering to try it today:

17.9 e.t.

Now we have to remember this is a stock LG3 305 with a 2 barrel.

i was, however, able to still spin the right rear tire.   And i did not load up against the converter either---i left off idle.

1/4 tank.

The 305 still had enough torque to spin the tire for about 6-10'.  With 2.56 gears!

Still couldn't get the 0-60 timer to work for some reason.

70ish degrees.   i have no idea what timing is set at and the only thing that is modified would be dual exhaust with flowmasters.


Stats:

Stock LG3 305 with rochester 2 bbl
Th-350C trans
2.56 rear diff gear non-posi
Off brand 235/75 r 15's
Weight---stock 1/2 ton
Dual exhaust with stock exhaust manifolds.  Flowmaster mufflers.

Wow, it's been almost a yr since my last attempt.   Today i, for some reason, had a hankering to try it again ( i did not realize the last time was 10/7/10).   i thought because it was cooler----this was at 10PM i would get a better time.

18.3  No wheelspin this time---i had to get a new tire (see post in the body section entitled "Don't be too cheap......")   A hankook optimo 727.

So i think the only reason why i had wheelspin last time was because i had off brand 15yr old tires?   Because there was no wheelspin the timer registered a slower and more accurate  since it reads off the transmission's output for the speedo cable.

i was amazed at the acceleration in 1st gear.

the timers should set off at the first sign of movement from the speedo cable so it would give you a reading if you timed the tree perfect with no delay
