D6VE-AA rods vs CJ rods

my current rods are D6VE-AA's but my engine builder is saying i should find some cobra jet ones for a little extra insurance at higher revs.

what you think or will the D6VE's be up to the task?

Im getting the rods shot peened, deburred, balenced etc but before i do... wanna clarify weather i should keep these or find the others.... or.... hold off and get a set of H beams?

cool Re: D6VE-AA rods vs CJ rods

Tell your engine bulder that the D6VE truck rods are the same as the D0OE CJ rods which he is suggesting, as both connecting rod forgings in question have the spot-faced rod bolt holes...unlike the standard passenger car rods that have the broached rod bolt holes.

Now, here's where it gets interesting. First, just because a connecting rod forging is a D0OE does NOT make it a Cobra Jet rod! Both the passenger car rods AND CJ rods were manufactured from the D0OE rod forgings...meaning that they were machined with either the spot faced bolt hole or the broached bolt holes...so know what you're looking at! Conversely, all D6VE truck rods are machined like the true CJ rods, so you can't go wrong there.

Second, I am of the strong opinion that a CJ rod is no stronger than a dime-a-dozen passenger car rod, even though the CJ has more material around the shoulder of the big end of the rod (because it was spot faced instead of broached). Why do I think it isn't any stronger? Because this is not where the 429/460 rods break. These rods almost invariably break mid-beam, and the CJ and Passenger car rods are identical in this area. These rods have been used successfully to 600+ hp although I don't think more than 500-550 hp would be a good idea for a really long term build.
