hey guys,
i have a NBS 1999 ECSB with the 5.3L/4L60E, 3.73 rear end gears,
my drivetrain has 105,000 miles on it and it seems a little tired...
I have a few ideas on what i would like to do...
either a 6.0L LQ9 swap with either a procharger or STS kit
---------------------------------or--------------------------------
a LS6 swap with a procharger or STS kit....... :burnout:
and as far as the tranny goes I would either buy a built 4L60E or a 4L80E depending on my needs...
If you guys could comment on what u think i should do please give me any and all advice you have....
One last question, would i be able to swap this over using my factory harness or would i need to upgrade anything??
thanks again guys.... :thumb:
