early 273 intake ???

I have a friend that has a supposed D Dart intake, I will have to look at it next time i'm there. he has it with a Mopar guy I've known for decades that makes a living with high end mechanical rare stuff. I was just curious as I have little knowledge of the D Dart. me, i'd be happy with small 4 bbl on that low comp 273 if it would be worthwhile!!
