Edelbrock part #71101 Street Tunnel Ram intake manifold is designed for 302-327-350-400 c.i.d. small-block Chevy V8's operating below 7500 rpm where low-end torque is not a prime factor. Great for engines with slightly modified heads. Will not fit 1987 and later cast iron heads. Use with cam kit #5002 for low-end torque or cam kit #7102 for top-end power. This manifold offers a polished finish for a brilliant shine and classic look.
