Something you have to keep in mind too Mopar Dave.... big cube engine can make a ton of power down low. My mech cammed stage VI 13-1 race engine sported a welded stock forged crank, stock main caps with ARP studs, stock LY rods with MP bolts, no block fill, and some light Ross pistons. I shifted at 5800, and trapped at 6200. It netted a best of 9.93 in my Mirada. We freshened that engine four times in 16 years and although it was worn to an "n'th" of it's usefull life, still ran really good.
