Re: Correct radiator shroud for 1970 SS-396 with A/C
Why do they NOT cover all of the Rad on a 70 ? Give a listen: First year for the 454 engines, The G.M. folks designed the shroud, Tested it and it worked. Lets get the new body design done and start building cars.
The 70 shroud was designed for a purpose and thats is why it has an open area on the left side. At the time Chevy Engineers were not sure if this shroud would work worldwide. Look behind the open area on a 70 B.B. shroud and what do you see. ( If so equipped) A power steering pump, That gets hot and needs cool air, Also an A-6 A/C compressor that needs cool air. The question was? Will these items get enough direct air flow? All Cars do not have P.S. & A/C, This design should work Bubba.............
A lot of Chevy designs were not pure science, But a lot of trial and error. They found out, NO issues with the P.S. pump or the A/C compressor, So lets change the design ( 1971) and see if, We cover ALL the heat exchanger with a shroud and see if that design will work.
A lot of items designed by the big three, Were cross you fingers and pray.
