Looking to buy/build 500-600 fwhp 360

Thank you for all the feedback. This project was started about 30 years ago by my dad, who passed away last year. I decided to go with a "Nitrous Under Glass" theme. The cool way the seat folds down and opens into the trunk will be perfect for popping in some nitrous tanks. Pretty cool to show them off through the back window. Also, I am a dentist so I always wanted to build a nitrous motor. It's going to be cool to pull up to the line, vent the nitrous like a raging bull and let her rip.

I like the direct feel of a stick-shift car. I know it is less reliable and consistent, but you lose horsepower with an automatic and a ford 9 inch. It makes more sense to scale back on the horsepower a bit and try not to lose as much through the drivetrain. My Corvette did not lose much HP to the rear wheels due to the 12 bolt diff and TKO 5 speed.
