Looking for advice, BB headers vs. HP manifolds

I’d skip right past the BB and just put a stroker SB in it.

You are absolutely correct sir, but, for reasons I can't justify or explain, I've always wanted a BB car but I've never had one. I think a 69 Dart is about the best looking car on the planet. So I'm willing to put up with some monkey business to get there. The 383 is all cold and lonely sitting in the shop, waiting for a Dart to come home to play...
