l96 in 07 tahoe hi guys my 07 Tahoe engine took a crap and wanted to replace it with a l96 and if it has dod,vvt I want to delete it as well.
first:does the l96 has flex fuel
second:could I use the factory Tahoe ecm after tunning to run the l96
third:would I have to change flywheel to use my 4l60e
fourth:would my all my sensor plugs plug into the l96 engine or would I have to use the 5.3 sensors

2. Yes, you can use the factory Tahoe ECM, you will just need to get a tune
3. Yes, you will need to swap over the flex plate from your 5.3 engine to the L96 to use the 4l60e
4. Yes, all the connections from your existing harness will plug into the L96

1. Yes, the L96 has Flex Fuel Injectors (50lb), also it does not have DOD but it does have VVT

Not really. Pull the valve covers, remove the rocker arms and pushrods. Once you have the front stripped down and timing set off, turn the cam a few times to get the lifters "stuck" in the lifter trays in the "up" position. Pull the cam, put in the new one and replace all the parts just removed. Very easy compared to the old SBC.

You will need to convert the cam drive and front cover over to non-VVT parts to use the non-VVT camsensor plug.
