That would be a 617 motor in 85. I don't know about california but the rest of the country did not have trap oxidizers.

I agree with Jim, its a pretty heavy car with a very tall rear end ratio so they were never quick off the line. A common problem with them was taking off in second which makes them unbearably slow.
