powdered rods are not weaker than those cast pistons they both should be changed for nitrous the reason i am looking for a dropin kit.

Yes the pistons are really good and even the rods but for stock when you start putting alot of power or nos on then the fail.

ive had nos before. and do you really want to do this work to it just to get some cheap hp and have to replace the parts you wear down and break every few months? which in the end isnt really cheap HP.

Its not the connecting rods that are weak, its the bolts for the LS3 connecting rods that stretch that causes the rod to slap then break. Make sure you buy the bolts with the forged rods or you will still have a failure.

Yes the rod bolt is the weak link. Callies with ARP 2000 is just about standard these days for a power adder engine..... but I think most forged rods will come with good rod bolts

Don't you think its ignorant of GM to keep using the same substandard rod bolts year after year when everyone knows you could get 650rwhp from the powdered metal rods with a decent bolt.

I just think for $35,000 its not asking too much for a better rod bolt.
