When talking to a rod manufacturer, it's necessary to talk to someone who knows what he is talking about, of course. Too many know-nothings are answering the phones these days. It is also necessary that the technically knowledgeable person understands that your application is one where you are operating at high power for a long time-- NASCAR, Le Mans, off-shore boat racing, etc--- NOT drag racing.

If moly rods would hold up in drag racing they would surely use them.
Using aluminum rods for faster accelration is not the reason as they go from zero rpm t0 8500 or higher in a
heartbeat and is one reason they use slipperclutches. If moly rods held up think of the money saved from not replacing rods every 8 runs or less.
I will be seeing a few top fuel racers in dec. and will get their answer. I suspect part of it is no give in moly rods
resulting in crank on ground or bearings being beat out. -to heavy for the piston speed.
Nascar-Le Mans use short stroke motors [ not 43/8 --41/2 in'' and don't make near the hp we do.
Off shore boats can't use the amount of fuel or very high rpms if they want to finish or have pits stops.
The 911 roadster only runs to the 4 because they can't run a big enough fuel tank.
I know that Fast Freddy uses over 30 gals fuel a run so don't compare Nascar-Le-Mans or off shore boat racing
with what were doing because their lacking on hp compared to high hp Bville engines
