    The interesting thing with 6.0L stock stroke forged cranks is they are the virtually the same price as a 4.0 inch or 3.9 inch stroke crank. Some candidates are: SCAT https://www.vpw.com.au/parts/SCT-4LS136365 GM L8T forged https://crowcams.com.au/product/gm-forged-crank-1

    Some really good advice here. Thanks. I'm pretty much set now on sticking with 6.0L. On the topic of reliability. I'm going to get forged pistons and rods. I'm tossing up if I should go with a forged crank or just stick with the existing stock cast crank. I'm not going to be going be giving it...

    I'm also still looking at cams. I contacted Kelford Cams for a specific cam recommendation. I filled out the details form and got this. "What you’re asking for is kind of mutually exclusive in terms of performance vs sound. I would recommend our SS108-C cam for your build. (228°/238° at 0.050″...

    I'm doing lots more walking without a car. I expect this rebuild process will take a few more weeks yet. The block is out of the car and at the machine shop. Apparently it's queued up behind many other rebuilds. The block still needs to be assessed for other damage and given the thumbs up...

    According to my research over the last few days. Cam overlap is a major factor in idle quality. More overlap, more chop, hunt, more noticeable. Less overlap, better/smoother idle quality, more stealthy. Negative better. Using this overlap calculator...

    Nice pistons you have. Do you think your iron block masks the sound if any? What's a good target compression? The piston above gives around 9.5 As a daily street car, my main goal is smooth, quiet and driveable on the street off idle to 4000rpm. I hear what you are saying on the camshaft...

    I've spent a bit of time researching. Pistons. At this stage, I'm favouring something similar to this. https://www.jepistons.com/product/srp-pro-4032-chevrolet-ls-gen-iii-iv-piston-4-010-in-bore-1-300-in-ch-14-40-cc/ I'm hoping this 4032 alloy has less cold start slap and less start-up...

    A rebuild is required. The #3 bore will be re-sleeved and block machined. No metal found was found in the sump. Everything else appears in good order. It will get rebuilt with forged pistons and rods. SRP pistons and Callies Compstar rods have been proposed. I want just a basic strong build for...

    Sean at Autowerks was pretty keen to get the car in when he saw and heard the vids. The rocker covers off found everything Ok up top in the valve train. The problem sound was diagnosed as cylinder 3 with low compression. Compression on other cylinders were fine. Off came the sump and here is...

    This clip is after a long drive and the car was hot. I started the car after waiting 60 minutes to let the lifters bleed down. It sounds worse now. I think it sounds like a truck. My wife thinks it's a tractor.

    Yes it goes away when it warms up. The lifters are LS7 lifters. The lifters and buckets were replaced 16,000 kms ago in Dec 2021 when the new heads went on.

    I was in Italy in October 2023. 5 weeks of museums, history, art, culture, beauty. We hired cars on 3 occasions and it was very easy driving in Italy. We had one true car day. Morning: Maserati factory tour Modena. We walked amongst the factory technicians hand assembling the Maserati MC20...

    C'mon @crew chief tell the story of what happened. Did your 700hp torque monster twist the hell out of the driveshaft engineered for half that? Is that your 10.67?

    I was not clear when i said "back to stock". I should have said that I reverted to the tune that was originally supplied by the auto rebuilder, Craig's Transmissions. I reverted to their original tune they provided for the 800hp build. They subsequently supplied a more drag race oriented tune...

    It's almost 2 years to the day that I created this thread and picked up the car with the blower and other mods. The car has gone from stock to heavily modified. Since then, I've done 15,000 kms and blown a stack of cash (pun intended). I love driving the car at every single opportunity. The...

    Auto Trans Toughened Rebuild 6L80

    Yes. I had the trans rebuilt by Craig's. It was the 800hp build. I did have an issue at the drags some months ago. It turned out to be a broken sprag clutch. Craig's did me right a fixed it under warranty. More info on my build thread here...

    They said it can happen if getting axle tramp. I don't think I am getting it. I can't feel it and don't see it in front/rear dashcam vids. I've already got full poly bushes in the rear. This was recommended to help get power down and was done at the same time as the blower install. Craig's did...

    I have the FDFI Harrop 2300 and thermal spacers. Fits no problemo. No clearance issues for the VF. I reckon 600 rwhp is plenty for the street. Any more is only good for the track or bragging rights. 1. Get the absolute best possible new high performance sticky tyres for traction. So far, I've...

    Video of the day Thread - read the rules before posting

    I raced from Sydney to the Gold Coast on the weekend. The race is 384 nautical miles. 55 boats competed. It took us 2 days 20 hours. Here is the onboard footage of the few minutes before the race start. A little hectic and intense. This is GoPro 360 footage which is cool.

    I went to the drags tonight and the car shat itself during the burnout on the first run. The engine is fine. It might be the diff, drive shafts or trans. The car limped down the track to the car park. Everything looks normal on quick glance. The car went off on the flatbed to the mechanic. It...
