I put a 68 318 B-Body radiator in my 68 Dart and it was 23" tall if I remember correctly. I had to use a flat radiator cap and the hood barely closed, so I believe it is doable. Is it a factory radiator and if so what are the numbers on the top tank?
It’s a Griffen radiator their tech sent me the info on. A 500027 number.just seemed tall compared to what came out ( of course nothing saying that it wasn’t a throw in from something else
