I had a brother in law do something like that with a 67 Ford mustang fastback.
I gave to him and only had one ding in the whole car and ran perfect with a brand new 289 in it. Some times you just can not be nice. The plus is that we are both older and wiser for our mistakes now. It's hard to deal with family sometimes but it's family so what can you do. I've got a friend that has a machine shop so I sent a neibor to him
and my buddy gave him a good deal on rebuilding a engine for him. A week after it's done this neibor is calling my buddy at the shop saying it's over heating and leaking water and all kinds of stuff. Anyway this guy calls me complain how my buddy messed up in engine, when he rebuilt it. So I go over to this guys house to see whats going on.
I have him start it and open the hood, I start looking and the water is comming from around the top of the radiator. The whole top of the radiator is almost completely rusted off. Yet this guy calls my buddy cussing him after he rebuilt his engine for 1200 bucks.
I called my buddy and told him what I found and said don't pay attention to this idoit, he almost burned up a brand new engine because of a bad radiator. I guess it didn't matter because two weeks later he drove it into a lake. What an idiot!!! Kurt
