Definitely an Impala as the right rear fender has the antenna and the flags above V on the trunk lid.
Bought mine in 1963 - had the 348ci, 3-2bbl 315hp with 3speed on the column manual and dual point ignition.
Drove this car for 1 year and traded this tired hot rod in on a Brand new 1964 Chev SS Impala, 327 CI, 300 HP, 4speed.
That's where the $385. comes in as that was my trade in value.
You could not buy the 3-2 mainfold for close to that today.
Oh Oh Oh WELL
