No power after timing belt change

1996 B2300 Timing belt broke at about 150k. Changed it out. Truck does not have any power. Revs slowly to about 3500 and then bogs out.

Intake sounds loud. Pulled air filter and connection to throttle body, no restriction. Pulled cat section of exhaust, doesn't appear plugged.

Need to check fuel pressure next. My son cranked the heck out of it thinking it was out of gas.

Any way to check ignition? Other ideas?

Im not familar with these motors but a few things come to mind..

is it an interfearance motor? could the valves been bent?

also, maybe when you put it back together, the belt could have skipped a tooth and the timing is now off

The engine seems to have compression on all cylinders when turned by hand.

Does anyone the correct timing indicators that I can verify?

These OHV 2.3 liter engine were not interference engines in the past unless Ford changed something.

Should have a mark on the cam and crank sprocket.

My guess is the timing is off. Pull the timing belt cover and check it again.

Set the crank at TDC on the front cover.

Line up the mark on the plate behind the camsprocket with the diamond on the back timing cover.

Line up the aux sprocket to the diamond on the back timing cover.

Rolled it over to verify time. Tried to start. After no start, rolled it over to verify it is still in time.

Seems like the timing may still be off. Is the crank supposed to be at TDC or is there some different procedure...?

I think I just figured out I may have used the wrong "timing" mark. There is a large indent on the plate behind the cam sprocket. I "assumed" this was the timing mark. And since I was doing this along side the road last night by flashlight, I didn't check for any other marks. It looks like there be a stamped arrow on the plate next to the indent on the sprocket plate. Looks like it may be about 3-4 teeth off on the cam. I will check it tonight and adjust.

What the Heck is the "indent" for on the sprocket backplate?
