So I am curious. How could the bottom pulley be on the motor if there was no harmonic balancer? The bottom pulley is held to the balancer with 6 bolts, so the balancer would have to be present for the pulley to even be there?blew up my 74 360 real real bad. so found one on craigs. took it home and saw regular bottom pulley but no harmonic balancer. checked engine stampings, yup it's a 360, w/ birthdate of 2/2/79. also has an aftermarket liitle plate w/ a series of numbers on it just below the head on the front of the block, drivers side. could this be a jasper or whatever reman number, and if they did something internally, would that explain no balancer? or did i miss a bulletin that there were 360's out there not needing external balancing? help please.
the OEM balancer/dampener has a rubber isolator between the balanced portion and the center, and it's not unheard of for that rubber to decay and for the two pieces to slip, throwing the engine out of balance. I speculate that either this has happened, or else someone took the weighted portion off.So I am curious. How could the bottom pulley be on the motor if there was no harmonic balancer?

Right, But the center part is where the pulley bolts, so that would have no effect on it being there or not right?the OEM balancer/dampener has a rubber isolator between the balanced portion and the center, and it's not unheard of for that rubber to decay and for the two pieces to slip, throwing the engine out of balance.
