can i get a little explanation on the "race in D" comment made earlier? that'd be overdrive on these trucks, thought that was the less desirable position for launching. shouldn't it be "race in 3" to eliminate the overdrive? it has something to do with using a clutch pack to drive 1rst instead of just the sprags, right? would love the schooling, then we can return to the subject matter.
And yes the D or 3 position in a camaro will apply the overrun clutch pack to help support the srag.

When placed in OD or 4th gear it will only apply the forward pack, what this does is transmits all power from the clutch pack to the sprag then then sun gear,
the 1-2 shift is the hardest load on the sprag, placing it in D or 3 will help this issue
The reason the overrun is no applied in the OD position is because the sun gear spins faster then the outer race in OD or 4th gear

Anyone ever looked into the 6pinion planets from PATC? They're spendy but they're also quality billet material and claims to pick up around .3 in a car that's already in the 9s... Supposed to change the gear ratios to make 1st and 2nd much close and make geared more like a 4L80E.... Again, not a cheap upgrade, but I think it's worth looking into for those kinda of gains...

Along with a billet drum sleeve
You can tell what a shaft is made of when it breaks, and yes even a 300m shaft has broke before but VERY rare. When one of these break it looks like someone sawed it straight down flush. Others it looks like you twisted a piece of playdoe.
