I can see that. We had a 67 327 4 speed car at Matt's shop I pulled the engine on to detail it and so some small repairs. It was a really tight fit. I can only imagine a fat motor. It really wasn't that bad, as I have a lot of experience on engine swaps on cars from about 83-98, so it went pretty smoothly. I have done about the same detail and repair on a 68 427 4 speed Corvette and although it was tight, it had a bit more room than the 67. That was a badass car. 427 tri power car.
