about to friggen break down in tears

Well let my brother borrow my car to go visit a friend and somehow the overflow cap popp'd off and engine overheated and is shot....
Looks like time for a rebuild...any suggestions....thinking forged crank, .30 over, heads worked and flowed.....
what I need is good parts makers...(brands) to rebuild with..
I'm upset but she'll be better stronger faster when finished....

You may be jumping to conclusions. These engines are resilient to overheating. I overheated mine a on a few occassions and never killed it that way. The overflow cap popping off was due to it overheating, not the cause of it. A fan could have quit, you could have had a hole in the radiator etc. Diganose first, figure out fixes later.

That sucks but I'm not sure why an overflow cap would do that. Are you sure your brother didn't just raise hell in it and overheat the car?

The overflow tank is exactly what its name implies. If the car overheats, water expands and will dump back into the overflow. Thats why there is a full line on there and you dont just fill it to the top. When it flows back into the overflow it will do so forcefully. That force is plenty to knock the cap off once its full.

not stock overflow and after getting it towed home, both fans working...verified this when he called and went to check car out....also water left in radiator (drained when got towed home had looked like oil in it)....maybe jumping gun but he said it started smoking and thats when he saw temp shoot through roof before he shut it down.....
go back to work tommorow so won't be able to trouble shoot until tuesday night.......overflow was turned sideways and cap off......radiator has no leaks...

No I mean overheat the engine that quick. You don't even need it if you top off coolant every so often.

If he wasn't paying attention to the gauge then who knows how long it was in the red.

I'm with you, it blew off when it overheated.
