Thats pretty impressive, thats that LS6 putting in work!!!

 

My brother said he hit the revlimiter in 3rd when i still had the automatic and 3.42s it figured up to 153. 6000rpms with 29.2" tires. The stretch he said he did it is about a 5-6 mile completly strait stretch on an old highway. I had the truck up to 5500rpms in 4th gear with the T56 still had the 3.42s and the same tires witch is 140 mph and it was still pulling. That was with my 300# buddy too. Truck felt a hell of alot more stable at that speed then my brothers 99 firebird does at 118.

If anyone wants to figure up there speed by rpms here is a link to do it

ive seen a little over 120

but i didnt want to go much faster then that. lol

 

unless im at the track i aint gonna do anything over a buck 20... to much risk

 

One hundred billion miles an hour

drag limited

 

139mph...stock..... only the speed limiter and shift points changed.......

 

about 125-130, the fastest i've gone and got a citation in the process

 

Actually it's an LS2

 

I've had mine shift into 4th on me which means i was goin 150 for that to happen. Felt smooth actually.

 

U know wat i had that first but i dont know y i went back and changed it... but i knew it still looked wrong...
