Q & A

What's in the Box

This complete Shotgun Bill Street Tunnel Ram Kit features the  Edelbrock 2-O manifold designed for use on 396-502 c.i.d. big-block Chevy V8s with large oval-port heads (1975 and earlier). Ideal for lightweight applications such as T-buckets or pro-street cars where low-end torque is not a prime factor. Especially suited to engines using slightly modified or aftermarket cylinder heads (9.5:1 or more compression is advised). Optimum power range is 3500-7500 rpm.

Includes unpolished manifold, two 600 cfm manual choke Edelbrock Perfromer carburetors, polished Shotgun Bill scoop with filters and linkage. Not for the faint of heart!


  1. Top has vacuum outlet for power brakes. 
  2. H.E.I. ignition will not clear manifold.
  3. Intake manifold will not accept stock EGR (Exhaust Gas Recirculation) equipment.
