L99 good choice for swap?

[Carbo]

I have a 69 camaro and I'm considering doing the LS swap. Right now I have the opportunity to pick up a L99 all Aluminum 5.3 H.O engine complete with all accessories and harness with ecu, swap fuse an relay box, a 2wd 4l60e trans with new pump for $1700.00. The engine has 50k on it but I don't care about the mileage as I'll be having it rebuilt locally by an engine shop (looking for around 600 hp motor).

First, is this a decent motor to do a swap with?
Second, are there any concerns with this particular model..L99 vs an LS2 or LS7?

I haven't done a lot of research on this topic yet as I am just beginning to explore but if I can pick up a good motor and tranny for this cheap I want to know that it is worth it with an L99.


Thanks in advance.
