Ive got an extra set from a 1992 s10 blazer, Z-block. What could I sell these for? Have about 72K miles on them...only reason why I have them is because threw a rod and replaced whole engine, and it had the heads already. Thanks!!
Don't throw them away, ask about $150 to start with, and see if anybody replies, be negotiable since they have 72K on them and they're not Vortech ones.
Also run a post on the fullsize board, as they used the 4.3 too. Good Luck.
