1981 dodge radiator

[Dan Brooks]

Hi All,
I have a 1981 dodge step side truck I'll soon be installing a big block in, Does anyone know what radiator would be a bolt in for this?? Thanks.

78 was the last year for a big block, I would get a radiator of your choice for a 78 with a big block

Anything from the 80's will work just fine and will bolt up the the radiator support without drilling extra holes. However if you are adding/keeping A/C then an 80's Slant six with A/C or HD cooling is the same size and configuration as a big block with A/C.
