Very, very nice!
Just the sound is a giveaway... LOL
Amazing and serious swap.
What do you use to tune the ECU?
Maybe regularly check that oil hose to the supercharger. It seems to touch the alternator mount. (Just me, thinking scuffing from vibration.)

Funny you mention that, because i just had to do this to run a colder plug due to me making a mistake on the ones i bought.
I just jack up the front and pull the front wheels. then all of the plugs come out easily through the wheel wells. The only one that is hard is number 8 due to the air box.

For the ECU, i just used HP Tuners and changed the data to a 5.3 with an auto trans and built the tune from other stock V8 tunes.
Now i changed the data to the 6.0 stuff but kept the transmission information the same.
For now its drivable, but not a good tune. I have an appointment with a tuner on the 14th to get it on a dyno this way i can get it tuned properly and see what power she makes.

Glad you had access to your plugs, makes life a whole lot easier. I'm doing a V8 swap on my ZR2 truck. I'm using modified LT1 exhaust manifolds that sweep up and over the plugs so I can easily get at them through the wheel wells.

Looks amazing! I agree with Don. . .definitely looks like a German car with how much is going on in there, but it looks factory. I'm sure it will be wicked once you get a good tune in it. Great work!

Ya im going to keep an eye on that Power steering hose. But have have it clamped in a couple places to attempt to prevent movement.
