Father-Son 1974 Duster Project
I'm not sure, we'll need to ask DaveBonds it's his scamp.
I have never been able to get anyone on this site what the manifolds on the 74 360 were like, and if they flowed OK.
I sure hope the 74 up 360 A-bodies didn't get the same exhaust manifolds as the 318 2bbl cars did. That wouldn't make sense.
