i've got a 350 chevy in my driveway with the #3 piston ring broken. what should i expect to pay if i take it in to a respectable machine shop to fix the one cylinder. or should i have them all re ringed.what should this cost? i'm gonna call around for some prices, but i'd like to know the ballpark figure. the engine was rebuilt a few years prior, maybe 10 or 20k on the motor, so it doesnt need a full rebuild. i just want it driveable so it doesnt blow smoke out the one tailpipe .is this something i could do myself? i've done head swaps, but never ventured into the short block.
