I'm about to have a new motor built. Chevy 355 double hump heads big valves. What is the pros to 6" rod to a 5/7"? What are the disadvantages to the same if any at all?

do a search in the archives. there's a ton of info there on that subject. lots of reading material! off the top of my head, the 6" gives better rod/piston angle, smooths out power band, likes the top end. AND Smokey Yunick says longer=better!
