I agree--Rod ratio is the most talked about least HP producing item in a modern engine today. I worked at a shop that did high end national winning circle track SBC's. Every other builder in the USA did 6 in minimum most did longer--BIG names I tell ya--we would get one in for a redo/ fresh up--dyno it--put our 5.7 rod combo in it and pick up a little--"Long rods are better" is a MYTH---yea I know about dwell etc ---build about a few decades worth of engines and you understand if the rod clears the cam and oil pan and keeps itself hooked to the crank and piston then thats all there is to it!!!!
