No, you are not nit-picking; the L27 has a different set of parameters and requirements completely different than the L36 engines, it is even more complicated on the hybrid ECM'* and the reason why still there is not a good chip for the L27'* yet. Even with the older cars, the ECM reaches the limits, requiring others to band-aid with the addition of the AFC.

Well I know my burn was based on a L27 specific program.

Interesting fact that they are using L27 code, modified for your engine. The addition of the SC adds a new dimension of the operation of the engine, SC and related components. When I replaced the ECM on my car, accidentally, I left the wrong PROM in the ECM. My engine would not run, would hesitate and would not shift to OD. Also, the acceleration was very lazy and I could hear knock. Was putting out all sorts of codes too.

if he has a SI EV6 block its still the SI, the EV6 casting blocks are the L27..i've got the EV6 on a 93 bonneville sse 3800 block in my garage (the one my Hybrid work is with)...

i doubt the harness/intake are a big issue but PCM are a different matter...
many of the guys down under also swap in newer 96+ harness'* and computers to gain programability of the PCM others have aftermarket PCM'* burned by companies down there, the problem is they really dont HAVE a Bonneville "Equivalent" their cars were not clear cut copes of our vehicles...they used many of the same systems but i bet alot of the rest is different...

so have any of ya been lurking on the holden boards as i have?

some of em are even on FullThrottleV6.com some good info to be had but just remember dont take anything at face vallue till you get a confirmation...Bickham, Dogsballs, Locksmiff are some of the more interesting posts (you should see their cars... )and they are on streetcommodores.com

i remember that there was a thread on SI cranks and rods and pistons and it seems that they recieved the same upgrades through the line of 3800 evolution (ie thinner rings etc) and except for the formula Holden engines all had the same rods and cranks as available in the US...the Holden formula engines however got forged cranks forged rods and forged pistons...you hear reference to these engines in one of my previous links

also i figured this might be of interest to the fiero crowd...flywheel/crank info with some Holden only goody parts (check out the dual disk clutch setup )

You can already get a dual disk set-up from a few vendors in the USA and not pay the Aussie prices. Also, while perusing the other websites for pistons, rods and stroker kits, I was in shock in the pricing and cannot believe anyone in the US would pay that much for these parts. I can get better and lighter forged pistons form CP, or Wiseco for a 3rd of the price. The same applies to the connecting rods too. As I recall, there is already a company in Detroit that offers a stroker crank. By the way, if you take a close look at the pictures of the stroker kit, the pistons shown are cast and not forged.
