383 or 400 ?

The one I got was out of a 65 fury, and it runs for $100 , I would do the heads, a cam, and regasket the whole motor. I remember the 383 as a screamer, and the low deck's fit really nice in an A body! A guy I know has a built 383 in his 68 dart , he has HP exhaust manifolds on it, he said it dropped right in, fit like a glove!
