I've got 2 406" motors and a 434" motor, i can assure they all run 350 balancers (neuteral balance) you have too look at the block too know the difference. Even the cheap rotating assy's come either neuteral balance or external balance, your choice.
Zip.
what about the freeze plugs? also its a factory balancer.
Factory balancer probably tells it best. The 400 blocks comes with both 3 freeze plugs and 2 freeze plus. The 509 blocks usually has 2 freeze plugs and are 4 bolt main blks, but the 511 blocks come with both 2 and 3 freeze plugs, depending on the yr. I've got a 509 on the engine stand right now that has 2 freeze plugs and is a 4 bolt main block. I've got a 377" (400 blk)in my Malibu that has 3 freeze plugs and is a 511 blk and is a 2 bolt main.
Bottom line Tony is that the ad was misrepresented and you should expect to get what you were told you were getting.
But i'm a high performance engine builder and a racer. I don't build many street motors, but have sold 4 rotating assy's in the last 6 mos. both 406" and 383's.
I feel more comfortable building a 383 or 388 than i do a 406 because the 400 blks have a tendency to crack between the head bolt holes and the cyliners or the steam holes and cause many overheating problem, plus the cylinder walls are very thin on the 400 blks.
I personally would rather have what you got than what was advertised.
