All the late model, 1962 and above, stick shift OEM radiators and stick shift cars came with the same radiator as the automatic cars did but had the built in trans. coolers plugged with NPT brass plugs The book I have shows that same part number for it in 1974 B bodies with both 400 and 440 motors with auto. trans minus the intermediate cooling IHTHs

i found this number 3673998 on the radiator in the car and it comes up for a 400 but auto. i also was unable to find a number that is a 4 speed only radiator? any insight? as mentioned in other posts this is a one owner car w/ 46k miles and the owner has changed nothing on this car. My white book shows 3673998 as 28" auto also but then it shows a 3673098 for 400/440 28" both transmissions. Could you have misread the 3998 and it's 3098? Ron

An auto rad got the tranny cooling lines on bottom tank... I don't think manual car would get the same.

I would bet it's correct and the white book is wrong or maybe not as accurate as it should be. Mine was printed years ago and I really don't believe as much care was taken with 72 and later data.
Look for the date code on the passenger side rail.
