Tru-Ram® Small Block Chevy Exhaust Manifolds, Cast Iron

If you're looking for the power of headers, a distinctive look and the dependability of cast iron, we have the hot setup for small-block Chevys: the Tru-Ram® exhaust manifold. We started with a clean slate and designed an exhaust manifold that will give you looks and performance never before available in cast iron.

• provides a tight-fit for steering and clearance issues
• Flows better than original Corvette manifolds
• Same performance as tube headers with classic ram horn styling
• Offers a distinctive look
• 2-1/2" collector uses standard reducers or tight tube extensions
• Includes mounting hardware and gaskets

Header Dimension Chart

Note: The exhaust port size is square and large enough for most round port heads. It measures 1.375" x 1.375" and should be sufficient for most small block cylinder heads. Variation in location of spark plugs on aftermarket heads makes it impossible to verify that the Tru-Ram® will fit all heads on the market, but it will clear most straight and angle plug heads.
