Very cool! 13.25@103 is decent for that combo.

I used to own a '69 C body convert with original 440...stock re-build (10.1 comp.) 906 stock heads with just a 3 angle valve job, Edelbrock CH4B intake, stock ootb Holley 750 vacuum sec. carb, Mopar .509 cam installed straight up, Hooker 1-7/8 headers, 2.5 inch FULL exhaust with h pipe, stock re-built 727 trans with a TA mild shift kit and TA 3500 stall convertor, a stock 8-3/4 w/3,91's and B-body SS springs. On L60-15 Pro-Trac tires the best I got out of that combo was 14.10@101 mph in the middle of July...in a 4,350 lb. car!
