400 rods are 5.565 long as I remember which is shorter than the standard small block 5.7 inch long rod.

So, you are going to buy pistons for an odd compression height? The deck height on a normal small block is 9.025 inches. Therefore, with a "regular" 350, the pin to deck dimension is 9.025-5.7-(3.48/2)= 1.585

For your combo, you have 9.025-5.565-1.74=1.72

For a 327 "normal" engine, the dimension is 9.025-5.7-1.625=1.7 which is close but the bore on your engine would be 3.875 plus .030 = 3.905 which is not a 327 piston.

For a 302 or a 283, the dimension is 9.025-5.7-1.5=1.825

Therefore, a 327 piston comes close but you will have the piston deck height wrong.
For the 400 rod, the journals are the same as the 350. The 305 crank is a wimp, dont know why you say it balances better......it is of a cheaper design with smaller counterweights.

This sounds more like an engine built from unwanted parts. Why not build a 350 and call it whatever you want? It looks the same from the outside so the "different than a 350" argument doesnt fly.....
