Hi Buddy, i thought this may be interesting and it was just a little bit. I didnt watch it all sorry. i dont have 20 mins to spend on something like this. Im a bit oposed to ARP drive shafts as i beleive they are too stiff and shockload the distributor drive gear. The 5/16 OE type shaft is, for just about all appications, a prolem free oil pump drive solution. If it does fail then its not becuse it wasnt strong enough or good enough in any way, it was something else that caused its demise. You have not convinced me to use ARP shafts.
That's a good point. I did cover it later in the video about how the shaft can contribute to spark scatter as the stock shaft twists easier. Its continuous wind-up and release caused by the pump would cause the force on the camgear to be uneven. However, I also spoke to someone about this, and they pointed out how this action helps alleviate harmonics in the camshaft. As with anything, risk ultimately falls on the end user. I am prepared to take that risk. But, I expect no one to follow. All things considered, the only things I can think of to generate +50lb/ft of force is either the pump bypass has to jam shut, the oil is too thick, or too high an rpm is trying to be achieved.
I've seen them twisted. No doubt this happened because the oil weight was too great.
