No need to spend that much money! I'm into my swap only $3500 and that includes buying the engine which is the pricier 6.0 LQ9 (LQ4 is cheaper), full gasket and seal set, headers, a/c relocator bracket kit, tune, and other small things. You can prob keep the trans you have and just buy a stand alone controller for it, and/or a flex plate adapter. You'll be well under $5k after you're done. To get an idea, my build is the one that titled "Just another LQ9 swap" on the thread list. I'm almost done with it, I should be able to light it off this weekend
