I pulled this running 68 302 out of a 66 coupe that I bought. I pulled the heads off to check the bore. The 68 block has never been bored, I'm selling both together or separate. I don't know what the block is worth, so I'm willing to listen to offers. I've seen the heads go for around $400 on Ebay, so that's my asking price, or best offer. The date codes on the heads are 7L30 and 7M2. I'll add photos of the engine this weekend. I already had the head photos on my phone.
