I'd get that 160 stat out of there, that's a little too cool and may not be allowing the ECM to go into closed loop thus hurting fuel trim and ignition, hence lowered performance. 180 range is a good median

$20 bet on the blown tranny mount.

And best bang for the buck to get the most power out of the engine, although it's a bit of work, ditch the TBI and rollover to TPI (dime a dozen used).

Oh, and unless the motor came from a truck/van, caprice maybe, never heard of a 350 TBI in a Camaro, they should all be like L98 350 TPI, LB9 305 TPI, and the 305 TBI eluedes me at this point. And if the motor is frankensteined out of a different vehicle there may be some control issues with the ECM?
