I picked up a 5.3 LS V8 out of 2001 Chevy Suburban with 113,000 miles for $250 and a 700R4 from a 1990 S10 Blazer with 90,000 miles for $100. I got both for $350 including no tax and no core charge. The motor does not have a computer or wire harness.

Which computer do I need and that is tunable and maybe even controls a 4L60E in the future if I go that route?

Which wire harness ?

Thanks

I would suggest getting one that matches the Intake you are running. If you are running the 2001 suburban intake, then get one from the 01-2002 suburban.

Ecm should be part number 12200411

wait4me,

The 12200411 ECM is used in lots of truck & cars for the 2001 time period. Does it matter which one get since it will have to be re-flashed anyway to remove ignition key security and re-tune for a bigger cam?

It will need to be flashed so it don't matter what one you get. They all interchange.

I just talk to the yard that is closing will get the 5.3, 700R4 with a 411 ecu for $350.


Thanks

If I get the 4L60E instead of the 700R4, which one would I need ? From S10 with 4.3? Chevy 1500 ?

The yard still has the 4L60E.

Thanks

Thanks

411 does support the drive by cabe and drive by wire. I highly recommendyou get a 4L60E from a V8 over the 700r4 as brackets for the downshift TV cable are more than the cost difference. Plus a V8 trans is just easier. 4.3L 4L60e is dimensionally is different than the v6 trans in converter/bellhousing area.
