Lets do a little bench racing...

Occasionally I Take Mine To The Track(73 Duster). It Has A Internally Stock 318 With 80,000 Miles With New Comp Cams 260 Cam And Lifters/valvesprings. I Run A Edelbrock Performer Manifold With And Ede. 600 Cfm Carb. The Mopar Hp Dizzy Is Set To 34 Degress Total Advance.the Exhaust Is A 2.5" Magnaflow Dual Setup With Balancing Tube. My Trans Is A Rebuilt 904 With A Transgo Shift Kit. With My Small,but Well Maintained And Still Fully Functional 7.25 Rear With 2.76 Gears, I Still Run A Average Of 15.5-15.6 @88-90 Mph In California. This Is Perfect For Me, Since Its A Cruiser. Hope This Helps. Does Anyone Think These Are Good Numbers For The Combo As Well?
