Have you ever heard of a "Devorak Machine" Dodge Polara
Dan "Davork" car with two "ELDERbrock" carburetors... ugh. 906 heads didn't exist in 1974...? And you won't be winning many nostalgia races with a XE268H cam.
That site is for antique cars anyway, look at the rest of the threads everything is 1910's-1940's at the latest.
