I just raced a buddy of mine on my 02 scsb 5.3, 3.73 open with his 00 scsb 5.3 3.73 locking. We did not even bother from a dead stop as we knew what would happen. However, we did froma a 25pmh roll. My passenger side wheel still came a little loose but still got good traction. I only have a UPD and he a has a K&N intake kit and flowmaster exhoust. I still beat about a truck length to about 80mph and I was still pulling slowly. My truck has 17k miles and his has about 39k. What is the deal with the 02 5.3's?

 

i dont know if this is true but from what ive heard its like this...

99': weak cam/weak heads
00': weak cam/strong heads
01'-03': strong cam/strong heads

im sure people have different opinions though

 

My '03 4.8 picks up pretty good, but its lacking the torque I felt on my '00 5.3 that I can definitely feel, but I like the way it feels like it squats....i dont remember my 00 doing that.

 

get some more mods on the 02 and we can line them up. i havent raced a 02 or 03 similarly modded 5.3, but i'd like to know how they run.

 

squats?

 

Does anybody know for sure why the 02s are a little faster? I thought they still use the same cam from 2000+?

 

i think after 99 they got better cams and tuning has gotten slightly better each year following

 

Sure...! First things first.... no sence in making more power if I can't hook. Next thing I am getting is an Eaton posi.

why don't you just swap rear ends w/ your ext. cab truck? if your other truck has 3.73's and an auburn posi i would.

 

It has crossed my mind. However, I am not to crazy about my Auburn.
