I ran the MP .557 in my old 440 combo and I really liked it. But I degreed my cam in and put it on a 104 centerline setting using my degree wheel. It ran 11.49 @ 116 best in my 63 at 3700 lbs with 906 heads and the Holley SD intake. It had 10.0 comp. Never even checked cranking comp since it ran so good. That is a nice size cam but you need to degree it in with the degree wheel since it is a large enough cam that it will make good hp but if not set right it can hurt the low end as any large enough cam can do in the wrong combo. I think it would work good in your combo if set right and it needs enough comp. Ron
