Shawn sent some pics last night. The drive train is out and dissasembly begins.
The always photogenic Ed.
Doing one last baseline pull on the 403. They use an in-ground DynoJet - also known as the "Heartbreaker". The numbers were down less than 2% of last spring. No adjustments of any kind were made. It's always been extremely consistent.
Next it's up on the lift. A keen eye will spot the LG GT2 coilovers and PFADT sway bars.
Everything unbolted and unplugged and the car is raised off the drive train.
I run an ECS tranny brace with an RPM 3.90 rear.
I change the oil very frequently - everytime I have the motor out.
So long to the 403.
Shawn will be sending more pics of the dissasembly, parts for the new build, machine work and assembly. We'll post the progress and build results all the way until I pick it up with the 427.

Shawn has the engine torn down and PM'd me below:
A couple things,measured your bores smallest part of the smallest bore is 4.0050
largest part of the largest bore is 4.0085-that's .0035 difference.Some bore had as much as .0025 taper and out of round-pretty much like every other "cookie cutter" engine.The pistons were 4.0005-so you had as much as .008 piston to wall clearance.
I'll send you some picks tonight but you can see where the main caps were walking around due to the stock main bolts.
I'm confident we won't see those kinds of tolerances when Shawn is done.

All broken down:
Looks like it was burning some oil after all.
Pistons and rods out.
You can see where all of the main caps were walking with stock bolts. For some reason I thought I had ARP mains.
16-18k on this LS2 chain. Being replaced with a Cloyes adjustable setup.
Bare block ready for some serious machine work.

We layed down the ground work for a killer intake to work with those heads-long runner low profile max flow.Hopefully we can have a prototype built while your car is still here so we can test it on it.
