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: Speedway's Tru-Ram exhaust manifolds. We started with a clean slate and designed an exhaust manifold that will give you looks and performance never before available in cast iron.

These compact manifolds give you plenty of room for steering and other clearance considerations, and have a clean, vintage-looking design. You get the performance of tube headers in a classic ram's-horn shape.

These manifolds will work with angle plug heads.

General Information

Speedway's Tru-Ram manifolds are built from durable cast iron and have a distinctive ram's horn shape. They flow better than original manifolds and fit great in a variety of street rod and vintage truck applications – particularly those with Mustang II-type suspensions.

They will not clear original-location steering boxes in 1935-1940 Fords or 1955-57 Chevy cars. Tru-Ram manifolds are also available in polished or unpolished stainless steel.
