Overheated aluminum 4.6 engine, is it trash?

[Pranav]

I hate fucking with engines that have had shit happen to them.

I had cooling issues with my first lt1 block that were never fixed until I threw it away and started over with a new one.

How much is a core long block used? Always better to start with a never taken apart salvage pull and let a machine shop take it apart go through it the way they want to.

I can't answer your question but I'm running a tired 4.6 and am planning a new build this winter. Recently I bought a running junk yard 2002 Explorer engine and plan to use that block/heads on the new build (after a machine shop preps them). They came with aluminum blocks and PI heads. You could do the same, starting over with parts that haven't been "cooked". Cost me about $300 for the engine.
