    After thinking about it (always dangerous) I should keep the VL Calais, and install the Holden bits I don't need from the VN. And buy an ok 5.0l to drop in.

    Supershakes (steves), $900 dollar dry sump is because he builds racecars all the time.

    By memory, it's a combination of a factory LS7 dry sump kit modified to work on a L98 crank, think custom collars/adapters made. He does all the fab work himself.

    He is also smart enough to know what to buy and where from, along with the many parts he has lying around.

    If he could do a kit for 2k fitted there would be a line of cars heading down to S.A to make it happen.

    Commodores have NEVER used Chapman struts, unless they've suddenly started using a driveshaft to locate the strut.

    ^^^^^This, nice EFI 5ltr and manual in the Calais would fetch a reasonable sum.

    It's getting out of hand now, even for me. My brother just tells me his neighbour has a 5.0l VS or VR that he only wants a grand for... Motor is good.
    Buys a car for a motor, then buys another car for the motor for that one. 🤕

    Use the 243 heads that come with an LS2 - they will not produce as much top end HP as the rectangle port heads, but will produce a stronger TQ curve & be more drivable. A reco on the heads with good valve job, stock valves, mild port work & mill to get to 12.5:1 comp is all that is required.
    Cam around 238/242 on 109 centres - none of this wide lobe centre bullshit.
    You may need to eyebrow the pistons for piston/valve clearance, can be done by hand with a die grinder, or send to SPS & have them do it, or buy new slugs that already have valve reliefs.
    Add good springs, pushrods & trunion upgrade for the rockers.
    Run on E85.

    Ditch the stock intake & use an edelbrock victor jnr with a 4 hole TB - much better transient response & more top end into the bargain.

    Grab one of those cheaper dry sump kits I linked you to, cheapest upgrade you'll do (in that it'll save you building another motor).
    By the time you buy a good sump etc you're 1/2 way to the cost of the basic kit.
    Another option is to buy dry sump bits second hand & make your own - but it never seems to work out much cheaper that way, all the little shit like drive, pump mount, pulleys & lines end up costing more than they would if you bought a kit & it comes out only a little cheaper.

    Almost every failure I've seen in an LS circuit engine has been oiling related, you can build it reliable without a dry sump, but it's not much cheaper, dry sump is good insurance.

    It won't be the cheapest engine, but it will be reliable & fast enough to not be cursing the lack of HP.
    I've got a couple built just like that, they make 320-330rwkw & run hard.
    Hey Tony,

    If someone dropped an LS2 on your doorstep and you rebuilt it as above what would it cost roughly ? Just curious... and someone has made a pretty generous offer on my Pulsar...

    It's the cheapest way to get the car running with a nice 6.0l. And as a bonus I end up with a car I can run on ch plates.

    If I didn't have to make a batch of carbon fibre parts, in 4 days this car would have an LS2 in it. I presume I can just drop the subframe out with motor and box, and bolt it into the VN? Same subframe surely. I was always told a VN is just a fat VL.
    One mod I might do is swap to a lightweight flywheel. I like the quicker rev for down changing gears that you get with a lighter flywheel.
    And the sump will need modifying.

    Had a quick look on eBay. This one is local, so might get it quicker.

    This is another option. I have ordered parts from USA that have arrived faster than from Sydney.

    I was informed a vn has a narrower track than a vl if that effects anything.
    I told them I once raced cars (total lie ) pissed them right off I will think of something bigger.

    That can be fixed.

    I just found some pics of what I did to my last VN.

    No more Torana's. And only 1 MX5. Technically it's only 3 Commodores and a Calais. , not so bad.

    This is probably the view of the VL you want to see.

    I have a 4 puck ceramic clutch, it works

    I will get a flywheel for under $500. I had a thought of showing a quick video, but I was almost home so made a tiny video. Probably the last time I drive the car. Went for a cruise to check out the cars at B.P Eastlink.

    How tall is that silly scoop?
    an easy fix is get a mate to drive in front of you at 60 then 80 then 100 and mark in on your speedo with some liquid paper.

    Not as tall as the gearing. 3:08 diff gears make 5th and especially 6th redundant. I will have to change the bonnet. There was a few cars with the same bonnet cowl at B.P. And an amazing amount of younger loser looking people.
