How do I identify my big block Mopar engine?
you can tell the B motors (350, 383 and 400) from the RB motors (413, 426, 440) by the deck height. Look at the flat portion on the front of the block next to the distributor. if it is basically flush with the rest of the block, then it’s a B motor, if that same area is raised, then it’s an RB.
