383 Body manifolds in an A?

i picke up a 71 scamp with a 383 stuffed in it. turned out to be a 383 hp, and matching h.p manifolds out of a 67 c-body. there was no mods done at all. now i never tried to take these off with the engine in the car though.lol

No such thing as a 67 383 with HP manifolds from the factory. The only 67 HP manifolds were found in 440-equipped B-bodies (GTX, R/T, and Charger).

The manifolds pictured right above are 68-69 C-body HPs.
