When Indy decided to make small block heads, we used our patented format: lightweight castings, long valves, and proper port volume. The 360-1 head works on stock blocks and also takes advantage of the 18-bolt head bolt pattern found on the “R” series blocks from Mopar Performance. These heads will transform your small block into a serious street machine, or a very reliable, powerful bracket engine. Since 400″+ cid small blocks are common, our 360-1 rectangular port head was created to fill the bill perfectly. Expected power bands will be similar to a 451″ cid big block wedge.
