I'm not familiar with the setup so just spitballing here, I assume it's something like this with an extension/adapter to the original input shaft? https://www.marks4wd.com/mfk129.html Where does the bearing need to mount, on the front of the shiny tube or using some sort of spider legs back to the b...

Nice work and thanks for sharing. I'd think an amp with high level inputs (is that still a thing?) would be simpler than modifying the head unit and just as effective. If memory serves a hard-wired phone input may have been an option in which case it should be easy enough to get an aftermarket bluet...

Might be this one?

Given the number of steps you're seeing it seems unlikely that there is a physical issue, you just need to tune it not to open so far. As long as the pintle seats correctly and it has a fairly consistent/incremental rate of opening then the overall hole size doesn't matter (other than noise). There ...

Have been driving it a little and tweaking the tune to be close before turning on all of the closed loop settings. Most of it was adapted from what I had on the Delco which seems to have been a reasonable starting point. I kind of miss having the tablet to display some ECU info but figured out how t...

@vlad01 The KC covers all use a thick flat gasket, normally cork but rubber usually also an option. As per the V8 ones in this thread. Tidying up some scope creep items this week. Prepped and painted the scuttle panel. It did need doing and I didn't have much choice since I'd already stripped the ol...

That was the old VK, cap is just the half-turn style so not great. I made a custom one for the Torana, it has a flanged boss that bolts to the flat surface with a gasket, and an o-ring on the cap itself. In hindsight I probably should have welded the boss to the cover when I filled the grommet holes...

Great, sounds promising. Haven't really done much with V6s in that area but based on V8 dimensions it doesn't surprise me that you only need a little extra - some guys get away with doubling up gaskets so they can make it look stock. I like the KC covers though on both engines. https://img.v8comp.co...

Unless you've got a very wild cam I imagine 560 is lift at the valve. If that's quoted with a 1.6 ratio rocker then it'll be around 350 at the cam/pushrod. The difference between the old and new style adjuster/nut is approaching 3/4 of the lift so gives some hope that the new style ones are pretty g...

You didn't say how much cam lift, but looking at photos on the web the arm design looks different and could quite possibly have a different pivot height so not sure that comparison would be much use to you. Yes the top of the adjuster nut is likely to be the highest point unless you've got some weir...
