408 Stroker up and running
Well finally got it together, very happy with how it came together a total of 5 months spending a few hours each day on it and parts to arrive. got the new 6.0L iron block and 4 inch crank never came with a reluctor wheel fitted, that cost me an extra $250 supply and fit. Cam direct purchase from Comp, pistons from Wiseco direct they were the only piston anywhere that would fit the combo, heads, head gaskets bearings direct from forum sponsors, most other parts from local sources.
Ok these are the parts and cost in Australian dollars went from water pump back to the clutch for parts $13,000. I managed to sell off new and old LS1 parts for $4200, block, heads, diff, TB, manifold etc. The total drive train package, motor, diff, installation and tune will come in at $14,500 ($1500 for tune)- $4200 on parts sold so out of pocket about $10,300. The intake pipe is a HSV pipe and still running a stock maf until its tuned "ok enough of that", its amazing how much the PCM can accommodate major changes in the drive train, very drivable considering it still has a stock auto tune. Stock injectors are still used will change over during tuning. I have retained the auto radiator and have run the power steering through existing trans cooler connection. Relocated the battery in the boot had small problem with a good earth connection now fixed. I have used running in oil and went for a drive to bed the rings in, its hard to stay civilized doing that. Ok Just need to find a good tuner.
Problem areas
Windage tray needs spacers to clear rods, included with the ARP studs.
There are two dipstick holes, one on the iron block, one on the LS1 sump normal position, needed to plug the hole in the block.
There is a bolt hole missing where the alternator bracket bolts on to, but there is enough there to keep it secure.
The extra weight does lower the front a fair bit by 2-3 inches no good if you already have lowered springs. No noticeable difference in handling.
Engine mount bracket setup on the iron block has a four hole setup but the Ozzie bracket only has three hole, it lines up ok.
On the Patriot heads there were no holes for the lift point (brackets) to bolt on, may be a problem lifting the engine back in.
Increased noise from under fast intake manifold is noticed.
tricky getting the spiral locks on the pistons.
power steering reservoir bracket needed shimming 15mm out to clear intake.
crossover vent pipes on front of heads needed bending down 15mm to allow intake to sit flush.
use a large heavy-duty plastic bag to wrap the engine in on the stand as it will collect a lot of dust over a long period of assembly.
Keep the machined parts like bores and deck lightly oiled as it will rust in no time.

I recommend to anyone doing this that they buy an assembled shortblock. You can see on my thread all of the problems that I ran into and I didn't even have to build the bottom end. Usually you can't do it yourself for the price that you can get one put together for.

I am currently wrestling with the tune situation and just ironed out my problem codes and got her to where she idles and is driveable. Just waiting on HPTuner and 42 lb injectors to dial it in.

The sump I used is the same setup as your GTO, when I fitted the sump I noticed that on the iron block a hole for the dipstick which is not the location to place it the GTO has a dipstick hole on the sump. Do the sumps over there on LS1's mounted back to front, does any of this makes sence. cheers

I have 04 GTO and just installed same setup except with 5.3 ET heads. Had same problem with dipstick. The factory motor had a plug installed and we removed and reinstalled into new motor. I ran into same problems as listed above. You will not be dissapointed in your heads or setup.
