So you are looking at getting a new or reman engine just to pop in a cam and run it? Id get a low mileage take out from a wrecking yard for $250-$1000 and run the **** out of it, and buy a turbo kit with what you save...

What do you mean will it fit?
A 5.3 LM7 is a 5.3 LM7, what is going to be any different about it if you get the right year.
1999 enignes are different by a little bit because of the longer crank I believe.
And I just re-read the details about the 01+ engine, they have a core charge of $2,500!!!!!. After you factor that in the $200 in shipping back to them for your core you are talking $6,200 for just an engine before you get your core charge back.
$3,660 after the core charge, you could buy like 3 used engines and get a machine shop to make them brand new again for the same price. Holy man is that like getting raped with no lube.
