how high can you rev Ls rods? I'm thinking of putting an LS crank in a GSR block and the rods will have to stand up to 8000+ rpms. I would be using ARP rod bolts for sure, but I'm not sure on the strength of the rod itself. they can't be that much worse than GSR rods... I would like hard evidence please. personal experience would be best. speculation won't help here.

 

i'd try the F/I forum, i think they'd know in there.

 

The rods are not as strong as the gsr rods. The problem is the rod to stroke ratio and the piston speed. They should be a little better with arp rod bolts but i wouldnt go above 8000 or 8200 with the ls rods. Do youself a favor and get some aftermarket rods. That will make you feel better when you are reving the crap out of it.
