440 build questions and any suggestions.

I use the MP .557 cam in the 440 in my 63 and I love it. I also use the KB pistons with stock rods and crank. 906 heads I ported and it comes out to 10.0 comp and good .042 quench as I used the quench dome pistons. I have the factory power drum brakes on my 63 and they work fine with the .557 cam. It stops fine from 116 mph runs and stops good driving on the street. And it runs on 93 pump. Ron
