Is it possible to swap the rods and pistons from the bottom of an LS1? Just drop the oil pan, and swap all 8 out? I'm trying not to drop the engine and tear it all apart just to swap the pistons and rods.

I used to know a guy who rebuilt several engines with the block still in the car. Always thought that was very interesting. Guess the main bearings were never part of the rebuild...LOL

i really hate to admit this but i have actually done this before. i wouldnt recommend it to anyone though. why wouldnt you just take the motor out and tear down/rebuild the motor? i replaced the rings in a 1998 LS1 because it had 240K and was smoking pretty bad. we removed the heads, oil pan and lifted the motor 5 inches or so. take out the rod bolts/rod caps and the pistons will just pop out the top. may as well replace the main and rod bearings while you are there though and dont expect to put another 100k on the motor as it is just a costly, temporary fix. good luck

Hell i've done it so many many times, if you ever worked at a dealer how do you think they do it? yep you guessed. Done properly on a engine that just needs freshing up its perfectly fine.

i guess if you are just changing the rings it is ok.(pistons have to come out from the top and go in the same way) but chances are if you rings need to be replaced so do your bearings
