Finally got my 340 motor back from a friends house who had it for too long…we had agreed to a price and he was supposed to be building it… long story short it never happened and I just found out today at the machine shop one of the cylinders had pits and would have to bore it out, problem is it was already bored .30 over. Is it a bad idea to bore it any more? Or is it safe to sleeve just the one cylinder? I’m trying to keep from breaking the bank, but want a reliable motor. I’m not at the drag strip every weekend and it’s not a daily driver but I would like to have a fun reliable car for shows and occasional drag strips. Or does anyone have or know of a reasonable deal on a good block or something rebuilt and can be tested or driven? Thanks just trying to sort this out sorry for the long post. Ready to get my 71 Challenger back on the road!
