OK. WE have 5 GM V6'*. 1 3100, 1 Turbo 3.1, 1 3.8, and 2 L67'*. We put PF-47'* on all of them except for the GTP, which we put on a PF-52 because there is no risk because of added lenth because it is in a different spot than the bonnevilles so it can't hurt to do it. Although we never let this car go longer than 3000 miles between oil changes (usually more like 2500), it is supposed to help the oil last longer because there is more of it. The plus is you get an extra 1/2 quart of oil capacity. With the longer filter we can put in an even 5 quarts, whereas with the PF-47 we can only put in 4.5 quarts. If clearance isn't a problem on your car, go ahead. If it is, don't do it.
