FI or built motor?
Well my goal as of now is to make around 550rw hp. I could live with less or more either way. The options are...
A) Built 402, high compression, nice cam, etc... should make 520+ from what im told on pump gas
B) Custom remote mount single kit, should make 500+ and retain great drivability. But ill have to hack the rear end of the car up pretty bad to do it how i want. See "my weaksauce" thread
C) Centri blower, ive got a chance to get a great deal on an F1R that i could run on the stock motor until it blows then build a nice motor
The overall goal is to have a very nice daily that can drag some pretty quick cars out there. My friend has an LS3 coupe with cam/full exhaust/gears/converter etc...his car runs hard and makes a little bit less then 450hp. I would like to be able to beat that car on this setup

Since you plan to use the car on the street and for straight-line acceleration the best bet would be to go with a centri supercharger. Not sure I would use the F1R, as that is a bit of overkill for what your goals are. I would look for something a little smaller like a D1SC.
With a S/C the car will drive stock until you put your foot into it. The N/A motor will be not be as streetable, and will probably cost more to build to get an equivalent amount of HP.
If you significantly increase the HP/TQ of your motor you will need to take steps to fortify/improve your driveline. The stock components won't hold up long to the power levels you are talking about.

Already have DTE brace, new clutch, headers, x pipe, etc... at the shop. The reason i would go with an F1R is so i have room to grow when i would build the motor. I know i want me happy with 5-600hp for long

Also, you will never be able to use more than about 400 to 500 rwhp on the street. You will just spin the wheels. Plus, I hope you have a big pocket book and a lot of time to spend fixing all the broken parts.
Speed costs. How fast do you want to go?

^^You also have to take into account your transmission, differential, torque tube, and axles. They were not designed for the HP/TQ levels you are talking about.

Nobody else has an opinions on this?

A rear mount turbo won't be the greatest thing with a 6 speed. Every time you shift, you'll lose spool and wind up NA for a while. They can work well with an auto.
Your driveline might hold up OK if you don't launch hard on sticky tires.
