Bad Distributor?
 

After a recent rebuild, my Z seemed very underpowered! Afr heads, zz3 cam, 24lb injectors, edlebrock exhaust. I should have between 400-450hp at teh fly wheel acording to afr. Went on the dyno and i had a meisley 232hp and 309torque. The shop thinks my distributor is going bad and becoming magnitised??? Air fuel ratio was 13.2 @ wot. Below is a link of my entire story. Anyway, has anyone heard of a distributor becoming magnitized? IF so, what are the symptoms?
