What is the rating for stock rods with arp bolts. I have 420 rwhp right now and just added a 90/90NW intake, an ASP pulley, and then I want to spray enought to hit 600rwhp. I have forged pistons, stock rods with arp bolts. Will this be safe or is it on the edge? rev limiter is set to 7000rpm.

Thanks

 

Holy *** dude lol 7k rpm, thats funny, how has that been working out for you? All anyone can do about stock rods is guess the safety, since there have been fluke rods that go out at 50k miles with nothing but a stock ls1. My guess is your good to go, procharger is also pretty confident about 550rwhp on a stock engine. I think your good, Im building an engine and I think im just gunna polish the stock rods and put them back in. I believe they are tempered.

 

Why is 7000rpm funny? I have been running that for 3yrs. If you are building an engine I would put in rods I wish that I did b/c then the engine would have been done. Now i still have the sh*t rods in. Anyone else with some hp ratings?

 

I have sprayed mine 200-250 all season they are lq9s with arp bolts but I wont say that im not scared that they are at thiem outer limits, with stock rods its just a gamble..

 

they're cracked powdered metal rods, pretty strong piece. they're stronger than the "pink" rods that used to be an upgrade to stock chevy rods. I would venture to say 700fwhp is when I would start to worry...
