Something ain't geeing and hawing with that combo. Of course there are "Happy" dynos and "Stingy" dynos. But those numbers seem about 25hp/tq low to me. When Dwayne an I talked about my cam for my LD512 build. We knew we were going for a street specific grind. And when it was all said an done. Even at .575 lift similar duration on a 112 sep SFT cam. It made 640hp670tq @ 5800 with a 850 carb with 10.25 comp and was a point fat on top. I remember the shop dyno guy asking me about my combo. I told him and he said that should make a nice 575hp grocery getter. I remember thinking if it only makes 575 i'll puke. He through the lever and looked at me and said damn.
