That is bad ass, your rig looks as though the factory had a 4BT option in the cracker box Bronco. Awesome!

What kind of Hydroboost set up did you use? I am building 1970 and still trying to get all the parts together.

Sure does to me also. Bleeding the injector lines won't help at this point. The air is already out of the injector lines. Hopefully it's an injector, or possible a broken valve spring. I wouldn't run it untill you eliminate the possibility of a broken valve spring.

The EB look great though!

if it was a valve spring the damage has already been done ,use a heat gun and take the temp of the injector ,high or lows at the injector will let you know which one has problems .

I suppose you could crack each line when idling to find which cyl is dead, too.

Still looking good. I agree with the others; I would resist running it more untill you find the miss. The air should work out a few seconds after it cranks. A spray bottle of water squirting the manifold will also show you which one is missing; it will stay wet longer.
