I was in that dilemma when I was about to purchase my crate BB. "Gee, for another $1000 I can get 600 hp instead of 535!" I ended up going with the 460 to save $$, and I guess I'm glad I didn't go for the bigger engine. The 460 is a monster, has more low end power than I'll ever use in a 2300 lb. car. Plus, I can only imagine that a hotter setup, with bigger cubes and 65 additional horseys will only make more heat. And heat is a major problem in these little cars with big engines. I would just consider all this, especially if you are planning on cruising in your baby.
