    Here is what I might consider - that LSX454 long block with this intake / EFI control:

    $17K is my quick estimate total swap cost - call it a wash with a built LS7, but this is an even stronger bottom end and more cubes and just a simple cam swap away from 650hp - but wow for 627hp and 2 year warranty the way it comes - that's pretty compelling idea and would make for quite a cool build.
