The 5.7 is a good engine. Tom Hoover is even impressed with them. He wanted to move the cam possition in the block on the old 426's but Chrysler wouldn't do it...at least until the 5.7 came out. I read that in a mag.
I got an extra 10HP out of mine with a K&N cold air intake. Edelbrock is claiming "7-12HP and TQ" with their headers. I've heard of a company that's bolting on 6.1 heads and some other mods and making ALOT of power. Now if I could only get a money tree to grow in my back yard... all I have is the fertilizer!
