Flathead engines have a low power output compared to a modern engine. I JWL book he said the stock engine made 79.4 HP not running a fan or orator gen. These engines didn't need much pressure and 10lbs at idle 20 cruising the city and 40 on the road. I use 10\30 year round with a good filter system. In the stockcar we ran a 40 wt racing oil at 50lbs, which usually dropped to 30 at the end of the race. Never had a problem with this system Thw bigest oroblem with an IC entine is a rich fuel mixture. And a bad cooling system. The pistons we use today are not made for street use, only a Hyper u tectec piston can keep the crap out of the oil, but only OFFY males them, but with a 75 year lod ring pack. Be nice if someone would make a set with modern rings and we'd hae a 2--K engine..
OH !!! And by the way the 239 flathead never made 100 hp nomater what you did thoit as long at you kept the stock cam JWL
