i think i decided on an engine combo. going with the 400 block 500 cu in stroker kit from 440 source and edelbrock victor heads. as for he cam and carb something big. I like the victors because they give me room to grow in the future. My initial goal will be for high 600 low 700hp range. w/ out of the box victors. i read a car craft article about them they are good for it.
