According to published weights I can find, the FA20 engine and transmission is 480lbs. The B58 is 306lbs and the ZF 8HP is 192lbs (498lbs combined). Not lighter than the FA20 driveline, but also a completely negligible weight gain for the performance difference.

1. Exactly.
2. Yes, it is heavy. Part of that is because cutting an engine in half requires the edition of some extra material and parts. There are two heads, but there isn't twice or a doubling of the heads in terms of weight. There is a trade off in creating a low and compact engine, but good to know I was correct, that there isn't an 80lb savings. I'm sure there would also be a small to significant handling penalty by placing an equivalent of three to four cylinders further forward and raising the COG of the engine. Depending on the racecar application, this could be detrimental to handling.
