does any body know where i can get some freakin ls1 piston rings i'm about to flip the **** out i've been seasrching all night and everything i find is for over bore or not ls1 at all. please help before i break something oh much would a over bore of .005 be would these rings fit on stock pistons i'm guessing not. the stock ones are 3.898 and the ones i found are 3.903

 

i have these written down for some reason... dont remember why. maybe some help.
probeindustries.com, motorsporttech.com, HorsePowerEngineering.com, compstarcomponents.com
dont hold me to it, but they might have something

 

ok nothing in there i looked at each one so either i'm just dumb or its not there

 

I did a Yahho search under Perfect Circle Piston Rings and got engineparts.com/parts . It's owned by Clevite which is a Dana co.

Hit "products" ...it's in Adobe format and they make them for every concievable engine ever made,it seems I saw the 4.8 and 5.3 Vortec listings,through 2003.

 

are they good rings couse napa carries those but i wasn't sure if they were any good or not.

 

so any more ideas as to where to get good rings and if the Perfect Circle Piston Rings are any good any body use these

 

I haven't used them but know they have been a well-known ring mfer for decades.

 

do i have to buy new pistons if i go to 3.905 bore from the stock 3.898 bore or will rings do?

 

Have you tried the dealership or do you want piston rings that can handle some serious abuse? Cuz im sure that any dealership worth its salt would be able to get them. Did you fry them or something??

 

no i bought a motor off ebay and wanted to pull it apart and check everything out and i was trying to find some rings that could hold up to some boost probably 7-10 psi daily at the least 7 couse thats what the spring in it is. are the stock gm ones good enough for that. and what all can i check to ensure the ones in it now are good enough to not have to swap.
