It depends on the alu. rod material.I have been searching for for a thread on this, have not found anything, what is considered a safe quench distance when using alum rods in a big block with a 4" stroke, spinning under 7000 RPM???
Not really a "mistake" per se. They'll work OK. Just plan for them.I know it was a mistake to get alum rods, but since I have them, and the Manley ones are what I have
You're probably thinking of the Jaeger rods. Some type of ceramic-aluminum matrix composition.Fwiw, we can buy aluminum rods now that are darn near as tough as steel rods!
Somebody and I want to say they are in KY sell's them, but I forget who??
My bad. New space-age tech type aluminum material here..
If interested, then please do a search b/c I've posted about this before on the sites.
In a 625hp engine the Manley aluminum rods are good for 125-145 passes at 8,400-8,600rpm past the lights with no issuesYou're probably thinking of the Jaeger rods. Some type of ceramic-aluminum matrix composition.
I don't have any experience with them, and don't know anyone who has.
Plain ol' Manley "Super 70" rods are just fine, but Manley quit making them now, I believe.
Hell, I still run the old-design Venolia rods in my 355". Never a problem. I replace then every couple years when I freshen the engine. My 355 has a pretty light piston and pin, but I spin it to 7600 on the shift and 74-7500 in the lights every pass.
