It's a tall deck block so standard big block parts like the intake wont bolt up, but they do make aftermarket intakes for these. There are some tall deck 454s out there, too. Most people dont build the 366 because they're an odd ball engine mainly for large truck use. But if it runs decent and it's cheap, what the hell. It had to make decent power to pull a school bus around. Paint it orange and slap an aluminum intake, a holly, some headers, and some chrome on it. Presto, you got a budget big block.
