sorry it takes me so long to reply but thanks for the pointers basically i dont wana go as big as i possibly can but was figuring out my options. i think that ill prolly stick with the 350 block cuz theyre a dime a dozen plus when people ask what ive got under the hood all theyre gonna get is "its a built 350." to thro them off a bit. but if someone out there (hint hint) has a good 400 block theyre willin to get rid of then id go with that.
