There are a lot of different flywheels, maybe six or more? between those two engines. Small clutch, big clutch, internal balance vs. external balance and then the 440+6 type of flywheel which is another variation of the external balance.

If you have a 130 tooth, internal balance flywheel you should be able to swap it between multiple Mopar engines including SB, B and RB. But only if the rest of the assembly is compatible. (bellhousing, clutch, rotating assembly balance, starter, etc.)
