67, he needs to look at the larger case versions (5" by 11" with 3" inlet and outlets) if he can still find them. The smaller cases ones (~4.75" by 10.25") with only 2.5" inlet and outlet bushings will have a tough time flowing enough exhaust gas to make the engine happy at higher loads and rpms.

Need a part number? 17769 is the offset center version that will fit the Hemi-powered car.
