Good; as it takes the idiot factor out of the equation at the machine shop, Fast; as it arrived at the shop in a couple weeks. I waited longer to procure the cam than the stroker kit.... NOT CHEAP; Having the over bore re-sleeved penciled out better than customizing pistons and rings however. Went with the smaller SCAT rotating assembly with the 3.58 stroke. I kinda dig my little 373.
