I was wondering how strong a set of stock LS1 connecting rods with ARP bolts would be. I've rad the rods were pretty strong from factry but I've never seenan exact amount of horsepower hey could handle. I'm rebuiding an LS1 and was wondering whethe or not to buy new rods
The weak point in the LS motor I think is 99 and older is the rod bolts so if you upgrade the rod bolts you are all in. My buddy was pushing 620 rwhp and 690 rwtq on a stock bottom end ls1 T76 single on an e85 conversion.
I have heard around the 500 range. Heard more and less, I wouldnt recommend just putting rod bolts in it, some people have had luck with it and some have had terrible results. A ton of threads on this debate.
