Need advice on a 340 stroker engine

""a street car for the most part. Driven on nice days and to shows
I am not going to be taking it to the strip and racing it really on any level. I was hoping to achieve in the 500 to 550hp or so."
My question is why 550 hp for this ? Just buy a crate engine drive it foryears when you sell the car numers matching will get you more $$ for some reason .. put lots of chrome and stickers and tell them you have 600+ hp at shows :;-)
