340 or 408?

Didn't mean to create this 8 page battle of testosterone , Literally just seeing if 500 hp is realistic in my street car and my options compared to a 360/408. I am looking at the 340 and if it it looks good I'll probably scoop it up. Maybe it's my downfall but again , I'm an old school guy whos ways are out dated but still work and I have a ton of fun driving my car and ripping some gears. Thank you to all who helped me and put their .02 in. Much appreciated!!
My daughter's 340 stock stroke, with Edelbrock heads not ported, Bullet cam, pump gas 10.7-1 KB pistons that are 15 years old, lightweight i beam rod, M1 intake, with 4.56 gears. runs 10.60s in the quarter mile. got to be 485 hp +or-, and its just a street car that is not driven on the street anymore. still has the factory radio. have fun with your build and driving it.
