Mishimoto X-Line Aluminum Radiator Plymouth Barracuda Small Block 1970-1973 - 3-Row Core

The Mishimoto X-Line radiator replaces the factory copper-brass unit in small-block 1970-1973 Mopar B-body and E-body cars with a three-row all-aluminum core. A stock radiator sized for a 1970s 318 or 340 runs out of capacity quickly once compression, timing or a modern cam raise heat rejection demand, and it runs out of it fastest in traffic and on track, where airflow through the core is lowest.

The core is a three-row brazed aluminum design with aircraft-quality aluminum end tanks TIG-welded to it, so there are no plastic tanks and no crimped seams to weep. It also carries an internal transmission cooler, which keeps automatic transmission fluid in its operating window without a separate front-mounted cooler and the plumbing that goes with it. Fans and a shroud are not part of this radiator.
