How to keep my Battery and Engine Secure?

[Deadman70]

Hey Guys need a little Help.

I just got back from vacation and I walk out to my truck to start it up and find that someone has flipped the hood and stolen my battery (just after I replaced it and installed a new battery holder, etc). A couple of questions.

1. Is there a way to lock the hood? A part or some kind of Trick?
2. If not is there a way to secure that battery so its next to impossible to pull out.

I would rather secure the hood since I have started putting money into this to restore it. I have A 1973 K20.

I was thinking about cutting some razer blades and putting them right where you life the handle... but I would probably get sued if the guy lost his fingers.
