Hy red450IH, if your block doesn't have the large holes for the oil lines to and from the filter then I would say it isn't setup for full oil filtration. Yes you could use your 216 bypass filtration system under those cicumstances. If your engine came from a truck, and as far as I know that was the only application for them in the United States, [we Canadians had them in Canadian Pontiac cars] then it probably had solid lifters, and the block would not be drilled for the oil to the lifter bores. You can check the lifter bores when you get the engine apart, if there is a hole through the block connecting all the lifter bores then you should be able to use hydraulic lifters, if there is no hole then I'm afraid it's solid lifters for you, hope that helps.
