Okay so few months back I was gonna build up my 99 trans am with 90k miles with ms3 cam, tfs 215 heads fast 92, etc and maybe a 100wet shot. Then I started thinking about a turnkey lsx 454 with tranny from texas speed. So what I'm asking is what would I need other than fuel pump and rear end to install it? Any help is appreciated, thanks in advance

 

Also forgot to ask what does a short block ls1 with 60e sell for used, 90k miles on both, stock ofcourse.
