I have a 2-row 26" one in my 74 318 Valiant. It cools just fine even in traffic when it was 90+ degrees out. I bought it from a seller on here. The install was fairly straight forward. The trans cooling lines had to be bent by hand a little bit, I had to drill mounting holes in the aluminum of the rad, and would have had to modify it slightly for a shroud. Overall it was very easy to install and worth it and it cools better than the old one even without a shroud.
