Any tips on changing rod bolts. Anything special I should know. I need to put new rod bolts on my rods tomorrow, and was just wondering. Thanks for any info. :)

rod bolts are one of the most highly stressed engine parts

ARP is the most comonly available better quality bolts,
YOU SHOULD have a MACHINE SHOP RESIZE the rods after swapping bolts to make sure they are correctly fitted and the rod does not get distorted durring the process,(SOMETHING THATS EASY TO DO BTW)

BTW
in most cases a set of AFTERMARKET rods ALREADY FITTED with ARP rod bolts may be CHEAPER than buying the BETTER QUALITY ROD BOLTS PLUS THE MACHINE WORK FOR BOTH MAG TESTING,POLLISHING,AND FITTING THE NEW ROD BOLT,RESIZING THE RODS, AND ARE FAR STRONGER ANYWAY

EXAMPLE
Scat H-Beam Rod Features:

Forged from a multi-stage heat-treated 4340 steel two piece forging
Each rod is X-ray tested, sonic tested, and magna-fluxed to insure quality
All surfaces are shot peened to stress relieve material
Precision sized and balanced right here in the USA on state-of-the-art equipment
Silicon bronze bushings for floating piston wrist pins
Precision alignment sleeves positively locate the rod cap
7/16" ARP 8740 cap screw rod bolts (190,000 psi) with 12 point heads
Fully profiled rod for stroker engines and cam clearance
Weight matched sets to ± 1 grams
Horsepower rating: To 700 HP
RPM Rating: to 8000 RPM

those 7/16" rod bolts are far stronger than any 3/8" rod bolts you can fit to stock rods, and even properly preped stock rods are suspect of failure at 450-500hp, keep in mind stress is cumulative, just because the engine does not fail the first or the 500th time you spin the engine to 7000rpm DOES NOT MEAN THE ROD BOLTS WERE NOT OVER STRESSED
