X-Mozilla-Keys:                                                                                 

This is my first input to your scene,so bear with me.
The stuff on HV chains keep relating to camshaft ,,,,,for what its worth
nearly all front wheel drive veichles use hv chain to turnthe drive 180
degrees coming directly out of the engine via mech.clutch or turbine.
the load on a chain in this llocation by far exceeds that of a timing
chain.
take the following scenario:
A toronado diesel [4000]+#,,,,,pulling a 3000# keel sailboat on a 2000#
trailer up from hope b.c. [ele 128' ] to the top of the cochahala hwy toll
both,,[ ele 6000] ft aprox,with the last km at 8 % grade.full throttle low
gear,,,,then coastndown to 2000',,,then up again thru rogers pass  aprox
6000'  no problem.
then go back for another similar sailboat!!
all TH transmissions have this chain 1" wide and are available from locall
salvage yards for 10.00$  [includes one chain and two sprockets]diys.

no problem.Then go back and haul another similar sail boat!

Well if we knew the speed he was going we could calculate the HP.
I will bet it was under 100 HP on that 8% grade. As he climbed further
up the HP of the engine dropped off of course.

I also think the chain is 1-1/2 inches wide and not one inch.
Perhaps even two inches. I could be wrong as it has been
almost thirty years since I put a Toronada TX and a Pontiac
HD 455 ci V8 in the back seat of a Firebird for GM.

Believe it or not if you were going slow enough you could pull
the Toronada and the sail boat up the 8% grade with ten horses.
It all becomes a question of how fast you climb. 

After the Toronada did that how long did the TX  last after that? :-)

Nobody is saying the chain will fail with short term use like that.
We are talking 2000 HOURS at 200 HP. Big difference.
