big block or small block

Below is a 400B/727 in a ‘71 Duster. I used a 440 Source aluminum W/P and housing for the later years which is an easy hose match for the small block radiator. It is a Summit aluminum radiator, electric choke TQ on a Holley Street Dominator, B body headers into the A body, of which I’ll never do again! But it did work with some BFH clearancing.

I really like that Duster.
