Did I Ruin my Engine? Crapped out timing belt. Interference Engine??? Long post 200

Well my 1989 244 automatic may be dead, I hope not. My main issue is if it is an interference engine or not.

Friday night I drove it down to to Newport in the snow and the car started losing power in the lower rpm ranges. I managed to get where I was going, the next day it died 5 miles from home, it had basically no power then it would surge for a second then lose power again. Worst of all it made some very loud and scary clunking sounds, what I imagine to be pistons ramming against valves. It sounded like a belt stuck on a pulley broke and kept whacking against the hood as it spun, but that was not it.

So I all this made me think the timing belt was shot. And indeed it was. It had not broken completely but there was a pretty big rip in it, and it looked to be slipping when I turned the crankshaft pulley. Also those little white marks were way off where they should have been.

I put in a new timing belt but since the sprockets were all off relative to each other I was forced to turn them individually to where they should be to match up with the notches. I read that you are not supposed to turn them, but I did not know what else to do.

So I reassembled it and started it up, it seemed to idle okay, I drove it around the block and it still has very little power, it will surge then lose power, and it will want to stall out. There was still some clunking sounds, but not nearly as loud as before. So I am wondering if it was an interference engine and I destroyed it with a slipping timing belt. Or maybe the timing is still off? As one may have expected when I pulled spark plug 1 it was carbon fouled and had a lot of gas on it.

10k miles on Cap, Rotor, ignition coil, ignition wires, Bosch Plat plugs. Clean Throttle body, no obvious vacuum leaks. I do have a new Fuel pressure regulator to put on it, and a fuel pressure gage to test it.

Do I have an interference engine? It is a 1989 244 automatic, from Boston.
If it is an interference engine I guess I will be doing some car shopping.
Does this thing from the FAQ only have to do with 700s and 900s?
I am all confused.

Thanks in advance,

Scott
