Amateur question here

Thanks

I picked up the shortblock today and the builder also said no one uses them. Seals are so much better now than they were 50 years ago it;s not a problem.

As for spacing, I'll be fabbing brackets and machining down the pulley spaced to fit a trigger wheel in anyway. I'll deal with that as I get to it.

Hi,
That is a mechanical fuel pump concentric on a small block Ford.

Yes, bolted to the front of the camshaft is the concentric for the mechanical fuel pump.

What the OP was asking about is the thin washer looking SRT on the front of the crank snout.

If I happen to have one, I'll use it. But I haven't seen one in so long it's kind of a moot point.

Obviously, proper spacing is pretty important. But, here's a point you don't hear much about. Once everything is bolted in tight, take the crank snout bolt back out. Make sure the crank snout is below the surface of balancer, where the washer sits on. If the crank snout is even with or slightly above that surface, it will be impossible to actually tighten the balancer down. And then bad things will happen.

Guess how I know that?

It's pretty easy to make a big washer of the proper thickness to fix that problem.
