484/284 & AC & PB isn't a good combo, too much duration & overlap for good low-RPM manners. I ran that cam in a 383 and it wanted a loose converter & more gear. Once it got some RPM, it was strong, but at low RPM not so much. The Engle grind I used in a 406" SB with AC & PB was 214/224 & .470/.504, CL was 110 or 112, and it pulled strongly, had great throttle response, 17" vacuum. Had a healthy sound.
I'd do something like that, Stealths, 9.5:1, either crank. If you want to sell off the 413, it's worth a bit more with its proper crank, but the extra stroke would provide more no-fuss torque in the 383. Look at Ross, JE, Wiseco & 440Source for pistons. IIRC Stealths are 80cc chambers. Use the FelPro 1009 composite .039" head gasket, get the pistons near zero deck, have the assy balanced.
