Engine belt tension for dual belt Spryte setup

Does anybody know the correct tension for each belt in the the double fan belt system on a Spryte 170 engine. The part manual shows the two belts, but part manuals don't give specs.

The '67 Falcon/Mustang manuals says 80 to 110 lbs tension for their single belt setup on the same engine. If I set both belts to that, thats a lot of load on the bearings.

well, the 'ol timers had a R.O.T. ,.... they used to say... grab the belt (usually at the top), in the middle , between the pullies.. and when you can just ''twist'' the belt 90 degrees ...no more/ no less... ''you're good'' . basically just enough tension not to slip on pullies, and not to ''over pre-load'' brgs. ,.... ( and that's if a belt tension gauge is non-avail.).
