Old BB stuff is cheaper and easy to copy someone elses build , HOWEVER if I could sell my 3-race motors and my 11-spare 440`s/parts etc.... I would be building a new HEMI with a pro-charger like tommorrow!!!!!!!
I`ve been intrigued with the new stuff for quite a while.
To me the old stuff is just that "old".
Either way do what you think will satisfy your needs.
