Yes, or pretty nearly yes. All Generation I small block rods are 5.7" except the 400 small block, which is 5.565".

I'm not sure what you mean by "What about building a 9/16" (3.5625") stroker from a 350?". That stroke makes 358 inches and would require a custom piston, custom crank and the 5.7 rods should work. A better stroker is the very popular 383. It uses the stock 400 3.75" crank in a .030 over 350 block with the 5.7 (350) or the 5.565 (400) or the very popular 6.0" rod that all the aftermarket venders can supply.
What I think is much better, is a 377. This is a .030 over 400 block with a stock 350 crank (3.48"). Federal Mogul makes what they call a thick bearing for this combo. Pistons are made so that you can use 5.7 or 6.0 rods. You doen't hear of these very often for a number of reasons. 400 blocks are hard to find. 4 bolt 400's are harder to find and everyone thinks they have to have 4 bolts. A subject that has been discussed here in the past. The third reason is that most people have a real hard time giving up 23 cubes and having to pay to do it. The urge is to build a 408, 412 or even 427.
The reason for a 377 is a rod/stroke of 1.72 and a bore/stroke of 1.19 . This is real close to the 327. What you get is a very high revving, big inch, small block, that isn't a really big buck engine. Also, I should add that this gives up a lot on torque to the 383. The 377 is for a light car and the 383 is a better choice for a truck. That is unless you think that an old truck should have a six, then my choice is a 292.
