does anyone know where i can get a new set of factory bore (3.898" i think) ls1 pistons and rings pretty cheap?

 

go on ls1tech.com and go to the classifieds, go to the wanted catagory and just put WTB stock ls1 pistons. i am looking for some as i bored my 5.3 out to 99mm (stock LS1) and i need a set. four people have replied back. one has a set for 100 shipped with 80 thousand miles, another has a set out of a remanned shortblock for 250 shipped, and i haven't got a price for the other two sets.

 

i have a nice used set. with rods. $100 shipped.

 

quick question on the subject, it you use stock ls1 pistons with the stock 5.3 crank and rods do you still need to get the rotating assembly balanced? I wasnt sure since you would be keeping the stock rods. Thanks.

 

You should always balance the assembly.The factories balance job is not that great imo.
The 5.3 crank should balance out without any mallory.Keeps the cost down a lot.

 

5.3 5.7 6.0 cranks are all dimensionally the same. rods too.
