Ok, do I give you the first build, or the second

4L80E with aftermarket converter $1,500
HPtuners (I already owned this from doing tuning on the side and have unlimited licensing for 99-02 F-body, so this does not get included).
Additional speed density and 4L80E segment swap through HP tuners $100
$9,650.. I am sure I am forgetting a coule things so let's just call it an even $10,000..
Now, for the new motor
Sold old shortblock, heads, cam, head studs for $2,750
