Lippy, you are going to get many opinions. Mine would be to go for the new engine. When I got my car it had a 427 SO in it. It overheated and developed a crack in one of the cylinders. Upon inspection the walls were very thin. It had been bored .030 over. I then had Keith Craft build me an engine using a 428 FE block. After 10,000 miles the intake manifold gasket leaked and it hydro-locked and broke a cylinder wall out plus other stuff. Again upon inspection the wall was very thin. I then ask Eric at Performance Engineering in Ross, Ohio to build another using a 427/428 FE block. After 3 tries he found a block that looked good. He machined it and upon inspecting it found a small crack had developed. After this, he and I agreed to go with a Genesis iron block. So far so good. Again, maybe I just had a run of bad luck.
