Yea Rick, I know the lemans rods are bricks. I guess the point I was trying to make there was as piston speed increases with a stroker the importance of a light reciprocating assembly becomes exponentially important to achieve high rpm duties. The Scat H-beams definately weren't designed with this in mind, more for a "budget" hi-performance build market. There are also high-dollar custom light weight pistons designed for hi-winding engines out there too. The LS7 went the hi-winding route, with titaium rods/valves, ultra light Mahl special cast pistons, light needle bearing roller rockers and small retainered bee-hive springs. There never was a factory built 427 S/O that ever spun like the LS7 does.. We've got 40 years of technology to thank for that..
