Hi All, I'm new here to the forum. I took a 57 T-Bird in on trade for my Cobra Roadster a few weeks ago. It's a D Bird with a 312, PB and PS. Can the balancer slip on these motors? The previous owner said he tried to set the timing and when he did it with the factory marks the car was really sluggish so he just moved it up enough to where he thought the car ran good. I put a load on it and it's not detonating. I think I feel a little harmonic vibration in the steering wheel at about 2500 rpm while cruising. Also can the timing pointer get moved? Last, what's the best way to find exact top dead center on these motors with it in the car. I have a dial indicator and magnetic base etc. Thanks for any help before I unload $500 on a balancer that may not be needed. Lex
