well first off you are talking about a low compression shortblock and a higher compression long block. two very different things. if you have a goal, say a turbo in the future, don't spend the cash twice. second that 383 power is coming through a different set of heads which you made no mention of work done to them or being done to yours. are you planning on spraying the motor or putting a large cam in it or what? gotta know your gameplan before telling you option a when really b is what you wanted.
