stock 340 rods

Yes they will live, with a light piston and good rod bolts (I had a set of JE pistons on stock rods with ARP bolts that I ran to 6500-6800 on a regular basis for 8 years) HOWEVER, why not just get some Scat I-beams and have some peace of mind? The Scats are cheap, forged, and light…couple that with a light piston and you have a cheap high rev potential….but then again, cheap and high rev V8 don’t belong in the same sentence, unless you already have some wicked valve train/heads/etc.
