The 20B is about $4000 US for a new long block. The cost of the conversion parts should be less because a few of the same electronics can be used, and I believe the stock 20b engine mounts can be used. For the LS1 engine, it's $2800 for a remanufactured long block, a completely new wiring harness and electronics will have to be installed, you'll need a new transmission bell housing, new clutch, etc, etc, etc. The final price should end up about the same.
150 lbs may not seem like much, but when it's 150 lbs of weight that high and that far forwards, it is a big deal.
