Your engine bogs when the secondaries come in under load, the secondaries are too lean. On a Q-jet, the secondary air valve is adjustable. There's a coiled spring on the end of the air valve shaft with a locking screw setup. Tighten the spring in stages,
your problem will probably go away.

Pope is right, I thought I read it was a Elderbrock. if it is a Q-JET then you need to be sure the secondarys are adj. properly. check this thread out.
