I frequently spin my motor to 6400rpm and was wondering how well these rods will hold up? I have ARP rod bolts and they have been polished and shot peened.

In the recent past, prior to NHRA allowing aftermarket rods, I was spinning my 5/16 FoMoCo rods over 8000 RPM frequently with no breakage. It sounds as though you have done the correct prep work to yours and they should live happily ever after.

I've got the same thing you got, coupe. I go to 6800rpm and have had no failures. ( I'm knocking on wood now!)

Mine see 7500 every pass, and I have never had a connecting rod failure. The rods that are in this motor, have well over 1000 passes on them.

Anytime I have ever had a rod break, it was preceeded by a spun rod bearing. The only downfall to the stock rods is that they are heavy.
