I used to run almost the same combo as I had a 10.5 comp 440 with 906 heads and the MP .557 cam. I used an 850 Holley DP and the Holley Street Dominator intake. I used the Hedman 1-3/4 headers as my buddy gave me them with the car when I bought it. My 63 is all stock body and weighs just over 3700 lbs with me in it and it ran a best of 11.49 at 116 with that combo and the 1-3/4 Hedman headers. Ron
