i currently have a stock 305 in my 1986 pontiac grand prix and i was wondering what would be the best engine swap for my car. its going to be a daily driver but also occasionally raced (weekend racer). im trying to choose between a 350, 383, or a 400. i thought a 400 would be the best because its the biggest chevy SB but i have people telling me to get a 350 because its a great street engine and theres also people telling me to build a 383. i never got a real straightforward answer on what to do so im hoping someone can give me good advice and help me with this desicion. i would appreciate all advice and suggestions. thanks.

BTW, this is the link for my car... http://www.cardomain.com/ride/727012/2
