haha actually i did some math on this badboy the bore is 4.19 and the stroke is 3.98 so if im right that comes out to 439ci? basically 440ci im hoping to have this thing in before prom. the girlfriend isnt too excited about it she just pretends to like riding in it bc she knows it makes me happy but thats all i can ask for she would much rather have a brand new benz or BMW....jeez people these days! who would choose a benz over a '65 ford
