With boost the motor you have now will make close to 1000. No reason the stock front suspension wont work. Cal Tracks, trans and axle of your choice. Better block and run it. We make over 800 on stock 360 cast crank and block. Using a 76mm turbo .550" hyd roller cam exhaust manifolds and Eddy heads. Plenty of naysayers but a pretty stock 727 and a Dana might get it done. I've had very good success running 900 through a 727. Know plenty of others as well.
