u/Sea-Bowler-6205

So I bought a 69 with the engine pulled and have been working on the engine. In preparation to put the engine in, I rolled the car down my driveway to my garage pad and it rolled fine.

At some point, I think while jacking it up and putting it on stands, I pressed the emerg brake. Now the front discs and rear drums are locked up tight. The brake cable released as it should, I can see it slide as I engage and release the emerg brake.

Does anyone have any tips?

I’m looking at a classic cougar with a Windsor that has been pulled out of the car and stored for who knows how long. A previous owner had put a 390 in it, and the seller wants to keep it.

How big of a world of hurt am I in trying to get the 351 going and installed? It turns by hand, and seller claims cylinders look good on bore scope

Any advice would be welcome
