Full set of cast iron rings that fit a 230 or 250 Chevy 6-cylinder that has been bored +.030" to a 3.905" bore size. Originally bought these for a Chevy 283 +.030", there are 7 top rings, 8 second compression rings and 8 oil rings. I used one ring to replace a broken one, so you have some extras for building your 230 or 250 6-banger. $15 plus shipping, will fit in a $5.95 USPS Priority Mail Small Flat Rate Box. Checks or money orders only please, I don't use Pay Pal. Please send me a PM if you're interested, thanks.
