No sarcasm. A 20% loss is subtracting 20% from the flywheel number, not adding 20% to the rear wheel number. If you're looking for 400RWHP then 400 = 0.8 x Crank Horsepower, which says you need ~500HP at the crank to yield 400 at the rear wheels, assuming 20% losses through the tranny and rear gears, which is a pretty good conservative estimate. With 480 at the crank you'll have ~385 at the wheels, again assuming 20% losses.

As for the costs, your initial post is pretty clear,

...would like to keep it under $2,000.00 on motor if possible.

Tech is simply telling you that your stated budget is unrealistic. Lots of knowledge here, if you take time to communicate clearly and don't blow smoke.
