Stock 385 rods are a huge weakness in all 429/460 stock builds. Better to buy stock pistons and spend your money on a performance rod setup if you buzz the darn thing.

I'm going to have to respectfully disagree with the statement above about stock rods. Stock 385 series rods are made of forged steel and have been proven time and time again to handle high power and high rpms.
Stock 385 rods are used in the FMS 460 crate motor that makes 550HP at 6250rpm, and were also used by Jon Kaase in some tests on his new P-51 heads making 807HP at 6600 rpm (this was in a 4.3 stroke engine). A 4.3 stroke engine running 6600 rpm works out to a piston speed of 4730 feet per minute. This would be the same as a 429 running 7900 rpm, or a 460 running 7400 rpm.
While some may say that Eagle SIR rods are cheap insurance, I don't believe they are any better than stock. If you are concerned about using reconditioned rods, new 385 rods made by Ford are available for $89.00-$125.00 a set from a number of sources on the internet.
