^^ I helped him build his Harness.
Nice pics Biz..let us know how that 6.0 does, they are beasts themselves..
Here is the rest of the progress from above..
I had to clearance the Oil Pan..this is the front of it where the divot is for the #1 Rod Bolt. I had to grind it down a little bit more.
Here is the Short Block for the new 408..

I had to Drill & Tap the flange on the Drivers Side of the Block to mount the Alternator Bracket.
Here is the 408 about to go in the car..
This is a Wiring Diagram that I made for how I wired the Manual Fan Switches that I have..
I adapted the Stock LT1 Fuel System into the 1999-up Corvette Fuel Filter/Regulator, and had a custom Line made to go from that to the LS2 Rails. The Regulator is mounted up front near the Fuse Box.
Notice my ABS Delete..it works like a champ..stops even quicker.
Here it is running with the new 408..
On the car I ran into a Wiring issue that I think was a bad communication in wiring, the Starter Relay on the LT1 car was not letting enough amperage through to the Starter to turn over the LS Engine. I bypassed it and it started up like a charm. I eventually took out the Relay and I re-installed it for the Neutral Safety Relay in my T56 setup. I put the Relay on the Starter Wire, and the Switch on the Clutch Petal is what activates it and allows the Car to start.
Here is the location of the Relay I had to bypass..
