360 Magnum building on an existing bottom end

I have a 96 360 magnum engine with less than 100,000 miles on it and the engine runs good. Can I just build on the existing bottom end? My plane is a big Muta Thumpr hyd. roller cam, stage 2 EQ heads 2.02 in. 1.6 ex., roller lifters and rockers, Offenhauser tunnel ram intake, dual Holley 450cfm or Edelbrock 500cfm carbs, MSD distributer and 6AL ignition box, A-833 4spd and an 8.75 sure grip rear end. Do you think the existing short block will hold together in this setup. Welcoming all reasonable info and comments.

I would replace the rings, rod and main, cam bearings. It's cheap insurance and a piece of mind. 100,000 miles and thing's can go south real easy, especially when you "tighten" up the top end and start spinning it in a higher rpm's then it was before. Oil pump drive and oil pump should be changed as well.
