Specs At A Glance

Good To Know

Q: Will this manifold work with my factory carburetor? A: Check the carburetor flange pattern against the manifold before ordering, since square-bore and spread-bore carbs use different bolt patterns.

Q: Does a dual plane manifold need a specific intake gasket? A: Yes, use the intake gasket set specified for your small block Chevy cylinder heads and confirm port alignment during install.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
