Finally after playing around with the idea of adding a spreader bar to my 427, I had brackets made where the bar clears the stock fan and pullies. The water pump pulley is from a 67 big block. It took a few made up templates to fit the spreader bar so it clears.
I think that's a useful addition. I've read comments that that big 680 pound engine, bouncing up and down, can eventually bow in the front crossmember under the crank pulley. The story goes that this eventually causes excessive negative camber. The solution is to cherry red the middle of the crossmember and bend it back to nominal. I've read of people doing this.
I am very interested in this as well.
It looks to me as if you may have manual steering?
And a 2 belt water pump pulley?
I am going to attempt the same thing on my 3 belt water pump pulley, AC & PS car.
Now that should be even tighter.
The third belt goes right where you have your spreader bar.
That's one of the joys of a non a/c, non p/s. non a.i.r., non p/b big block car, a bit more room. The water pump pulley and belts are for a 67 big block Corvette. Hasn't had a smog pump in over 50 years and I didn't like the 3 groove pulley without a belt. This may all change if I ever decide to put the smog pump ack on.
OFF the wall.....my frame is within 1/16" of factory dimensions...250h.p. engine...
Do I really need a spreader bar ..... or for strengthening the frame add one anyway?

I could DIY a bar in a couple hours.
There shouldn’t be any fitment issues on a small block with any combination of accessories. Very easy to DIY, but the ones sold by vendors are also fairly cheap.
I would say they’re worth it, if not for keeping the frame more rigid in the front, it also prevents it from sagging over time.
