I am going to look at a late 70s 260 that has been sitting for a while. I have no doubts it will have the plague we call rust. How far does a frame have to be before you guys would try to repair? I can get a pretty good deal ($500 or less). I was hoping some of you may have pics or examples of what you've fixed before so I can get a better idea of whether or not what I'm looking at can be salvaged. The car has a clean title, just a bad motor. I plan to swap in either a SBC or 1JZ and push around 375-450whp max, maybe less depending on how the power/weight ratio works out. Point being, I expect to do some reinforcing anyway. I've been looking for a cheap Z project for a while and one kinda fell into my lap, if I want it. If anyone has any examples of repaired frames I'd appreciate suggestions or ideas before I go look this car over. Thanks everyone!
