Why take a chance when i built my stroker i knew the driveshaft and yokes were the weak link, i broke one of those right off on my duster,and your stroker is putting out more power then mine i have billet on there now,not worried about breaking anymore..
Why do you ask? I would go with the 7290 and a driveshaft loop. If you break the 7290 and your running a 904 I would guess the 904 would also be in pieces scattered throughout the car. You need to protect yourself first then the car.
