should be the same, and that looks like the 5.7...is that what yours has?
is yours the same body style?
It looked like a 5.7 but mines a 5.3.
then no it wont be a direct swap...i thought the 2000 tahoes were the 5.7 older style motors?
stick with a 5.3
How bout a 6.0?
that is a 5.7 cpi vortec not a 5.3 ls vortec motor. Its an older design than what you have so it will not work.
99 Suburbans are old body and have the old engine. You need the LS style engine.
Yep thats the old 1950's original "small block chevy" that been
around since the dawn of time.
You need a Gen-III Vortec.
Search for a "LM7" motor. That is the model number for the 5.3L
LR4 .... 4.8L
LM7 .... 5.3L
LQ4 ..... 6.0L
LQ9 ..... 6.0L
will all swap over pretty easy for you.
