Ive got an 08 ly6 and I want to put aftermarket rod bolts in but not sure which ones. I know theres katech and reg arp and arp 2000. Ive mainly been looking at the Arp ones. But which one should I get. I know arp2000 are over 2x as much but are stronger which never hurt but do I really need that. Im not going to be boosted and I will have 150 shot of nitrous on tap since I already have the system on the 4.3, but not sure how often Ill use it. What will be done to the engine is, vvt cam not sure which one yet, ls3 intake valves, ls3 intake manifold and tb, longtube headers, underdrive pulley, stock rotating assembly and otherwise stock heads. Engine has 8,100 miles and will have a t56 behind it. I know theres no real overkill in strength but theres a big difference in price and at what point is the older arp bolts not going to hold up anymore? Ill probably get flamed for this ha.

 

Boy do I feel stupid I just looked at summits site and the reg arp are 89 and the Arp2000 are 110. I could have sworn the arp2000 were 200 bucks a month ago when I checked prices.
Heres the reg ones
