383 Radiator and Fan
What year car are you putting this in?
67 68 and 69 will all be ABOUT the same as to fit.
67 uses a different shroud than 68 69 but all V8 shrouds of the year are the same 273, 318, 340, 383
The 67 has a slightly different shape at the lower rad input tube and impossible to find.
The 68 69 are reproduced.
IMHO I would go for a OEM Copper brass big block rad and get the fan you showed.
I know of 2 BB darts, no shroud and they run fine in 90+ temps
My 273 same, no shroud and cools fine.
There are different lengths spacers. An ad for the rad and spacers will get you what you need
