    Burnout car? Didn't think you could get an LS/carb combo registered...

    New NCOP (N stands for National) says emissions have to match the motor, not the vehicle. Just tell em it's a 350 chev if you wanna be dodgy.

    Apparently you can't register a commodore LS with carb in HQ but you can register HQ with a LS crate engine/block and carb as it's not from a car with predetermined emissions requirements and will just have to suit HQ emissions. which is another reason I wasn't going to start with and old LS1 or 2 out of a commodore.

    Interesting. LQ9 is out, i've been down that road. Has to meet the equivalent US emissions for the truck it came in. I'm going efi though, so doesn't really matter.

    So basically it has to be an aftermarket block.

    Was your LQ9 a used motor from a GM truck/suv or a brand new block?

    Hi, just copied this out of Street machine in regards to a guy wanting to put a LS 5.7ltr and 6 speed out of a commodore into a HQ in VIC.

    The Rule of thumb is that you need to retain the engines original pollution equipment, regardless of the age of the vehicle into which it's being transplanted into. So if you're using and engine from a lter commodore, the transplant would have to retain EFI and other original emissions kit such as catalytic converters, charcoal canister etc. If you want to simplify things and run a carby, you would need to start with a new block,( ie crate engine or build up an engine from a after market block), as it will not have a engine number and therefore have no predetermined emissions history. Remember, the registration authorities will use the engines existing number to determine it's date of manufacture and therefore it's emissions requirements. if it doesn't have a number, it wont have a history - it's a unknown entity. therefore you just have to maintain the HQ's original emissions specifications. going this route will allow you to run a carburetor atop a modern LS-based V8 just like we did with our Precision 427.
    Is a new LQ9 block from like eagle no good for this? or does it have to be like a Warhark or LSX block?
    cheers,
    Wes.

    Hmm, my LQ9 was a 2nd hand core. Engine builder told me they don't have engine numbers on them. The number is cast into heads from factory. Only writing on my block is "6.0L"

    Might be right with an Iron block..
