Bummed out

I think it's safe to assume the car motor is toast. If it took out the block and the heads, the chances of the crank surviving are slim. But, since taking the motor apart is free, take it apart and check it out, if its good set it aside, along with any other salvageable parts.

It's hard to tell from your post, but did the machine shop extract the bolt? If they did all is probably good.

Here are some possible options:

1. Tear down and inspect the truck motor, if it looks good, buy a set of rings, hone the block, put a re-ground hughes cam in it, re-use the non reusable bolts, throw a set of headers on it and tune it and you'll be at 450-475 HP and run it until it blows up, or wears out. It'll probably last until your infant is 8-10 Years old, maybe longer.

2. Tear down and inspect the truck motor. Buy a used 6.1 Hemi forged crank off of Craigslist for $250.00, buy a set of the stronger (though still powdered metal) 6.1 Rods. Throw in a set of aftermarket forged pistons, bumping the compression to 10.5:1. Clean up the stock heads yourself, little gasket match and pocket porting, it's ridiculously easy to get 5.7 heads to flow 300 CFM. Put in a big cam with just under .600 lift. Finally throw a 150 Shot of NOS. Naturally aspirated 525-550 to 650-675 with the NOS.

3. Build a stroker. Get out your wallet. Finish sometime after the kid finishes college.

I have a 6 and 9 year old. I had more free cash spending money in college working part-time and living at home than I do now. The key to moving projects forward is to develop a well thought out plan and then stick to it.
I know it's really hard, my motor has been sitting on an engine stand for two years because of a lack of money. This summer I was finally able to build the ECM and hope to have it running on a stand by the end of winter.
