Thanks.
We found shrapnel inside (under the intake manifold). One of the spark plugs was smooshed down too.
Looking at new engines now. Ugh.

Very sorry for your misfortune, but on the bright side, now you have so many options.

If you have the original block, I'm sure it can be machined. You can choose to overbore it and add a mild cam, and add something like GT40 or Edelbrock Performer heads.

If you don't have the original block, but you want to take the car back to original, WCCC sells rebuildable cores that they'll date match to your car.

If you don't care about originality and want to go the cheap route, there's engine exchange places that sell remanufactured motors fairly cheap, usually with a one year warranty.

You can also order a new crate motor through Jegs, Summit or CJ Pony Parts. They have stroker options where they can get 500hp out of a 302 block.

If you love to deal with wiring, you can score a late model fuel injected 5.0 and drop that in.

Two things to remember:

- If you go with a 70 or newer 302, they have 4-bolt crank pulleys, so you'll either need to change the harmonic balancer to make your 3-bolt crank pulley work or buy a 4-bolt crank pulley with 3-bolt spacing of the Vs.
- If you go with roller heads, the cool Cougar valve covers won't fit.

Ouch. Do you know if the engine is the original? If not, I'd be looking at new/crate.....but it's not my $$$, so.....:shrug:

Yup, that guy, the hooligan.

Somewhere out there is a tree, tirelessly producing oxygen so you can breathe. I think you owe it an apology.

I honestly don't know. But assume it is. How can I tell?

Oh man, that really stinks. Reminds me of when I lost a valve on the highway in my 66 289. When I pulled the engine apart the valve was actually imbedded into the piston. I still have that piston around somewhere.

The failure was in the worn valve guide and valve stem. However, it was a big backfire under hard acceleration that led to the failure, and I finally traced that down to bad wiring on the back of the ignition switch which would heat up and basically shut off the engine momentarily.

It was the original engine in that car, so I had it rebuilt bored .030. I think it was about $3k all said and done, but that was back around 2001.

I bought someone else's rebuild, as it was local.....

I would say that if the date on block is close to date of heads (4H12) which is Aug.12 1964, then the engine is not original to the car, way to early.
