weight difference h22, b18, b16

What's the difference in weight between a h22, b18, and a b16. I hear people talk about how a h22 will kill a crx's handling. With the right spring and shock set up though I don't see why it would make a difference. You could also have a rear mounted battery for incresed weight distribution. Unless there's just an extreme difference in weight between these motors please let me know if I'm missing some other detail. Thanks.

Any info anyone?

I highly doubt that anyone here has those three motors sitting around so they can weigh them, and no one wants to answer because its just assumption.

I think the H22 is about 70ish pounds more than the B18 and 16. I highly doubt there is any noticable weight difference between those two motors.
