Simple question. What do y'all think about these rod bolts? I'm going to be putting a rotating assembly in my 355 SBC soon, and the assembly comes with the ARP 8740 chromoly connecting rod bolts and forged eagle rods which eagle rates this set up as good to 6,000 RPM... However, I'm considering purchasing the ARP2000 connecting rod bolts to use instead (which are $150 for all 16). The only thing is I'm trying to decide if I really NEED them. The assembly is only a street kit with hypereutectic flat top pistons, and I won't be taking the engine much past 6,000 RPM anyway due to the camshaft's advertised RPM range. What do y'all think? Is it really worth the extra $150 if it won't even be used in a high RPM high performance application anyway?

Don't waste your money.

Eagle and most other rod makers under rate their products rpm capability to ensure users don't generate too many failure complaints(cover their butts, so to speak.)

The ARP 2000 bolts would be necessary if you were going to try to run them to 7500-8500 rpm...and you wouldn't be using hyper pistons for that, would you?!!

By the way thanks for the input eric. Now I can feel better with ny decision to keep the rod bolts that eagld provides. This motor might see 6200 or 6300 on occasion, but realistically I'll be shifting at 6k. I even read an article by hot rod magazine in regards to the different alloys, and even one of thr guys from eagle said it isn't uncommon for guys to run the 4340 rods to 7k when when eagle rates em at 6k.
