If the block is a true full flow motor, you should have the larger oil feed and return lines, i actually forget the size. Runs all of the oil out of the galley into the filter and then back into the galley, under pressure. So all of the oil is filtered. The earlier blocks, and even some later blocks, for example the Canadian Pontiac 261 blocks, have the smaller bypass oil lines. That is the oil is essentially bled off the main galley, sent to the filter, and then simply dumped back into the pan. Only some of the oil gets filtered, so to speak. The trick with the bypass motors is that you have to use the smaller lines to restrict the amount of oil coming from the mains or else you will bleed all of the pressure from the motor and kill the bearings. Not so with the full flow. The beehive filter is strictly a bypass filter and so is opposite in that using the beehive with a full flow block will starve your full flow motor which is of course something to be to be avoided at all costs, lol.
