The 360 has the largest main bearings of Chrysler OEM V8s. I'd not put $$$ into a forged crank, buy instead a new 9000 Series from SCAT.
Also the SIR rods have been good for the last 4 years or so but I'd replace them with SCAT Pro series. There is no inherent superiority of H-beam over I-beam, and horsepower ratings for connecting rods are bogus from the start. Having said that, the SCAT have several good points, material, 7/16" bolt size, and low weight especially compared to the stock rods.

By keeping rpm low, you are extending the life of the engine.
