Whats there to tune or drive on the road, as you posted a lil while back to having a defect notice on the car and no rego. Regency defect inspections dont like cams
How hard is it to use a timing light on a carby 6cyl, how hard is it to recon a carby, how hard is it to adjust valve train and set cam in and set the idle and fast idle with auto/manual choke, how hard is it to set the spark plugs @ a child can do it, nothing complex, its not rocket science.
Diff and geabox ratios determine how the power output of engine/cam is delivered and put down on the road and the driving attributes of the combo,
no straws are harmed in the process, just personal choices on what gearbox/diff are used. Obviously the TUNE will affect the delivery in conjunction with the chosen ratios, known as cause n affect.
Low diff ratios used with a cam are not good matches from all the well documented facts have already proven.
What you posted ^^^^ above is absolutely nonsense @ fake bs news @ nothing relevant with this post discussion or any known true events.
