That would be the 5.7L / 350 Vortec.
YES The above answer is right. But the problem is that you will have to change the 97 computer,fuel pump, Engine and transmission wireing harness. You will also have to put the 700R4 transmission in that 97 Tahoe. Reason being is that the 91 computer that you HAVE to use won't shift the 4L60E that's in the Tahoe now. Your best bet is to put a VORTEC back in the Tahoe.
It means that its Chevy's top of the line model for that truck the best you can get with all of the options possible for the Tahoe.
the best would be unleaded
