Can someone please let me know an accurate outside diameter of an LS pilot bearing and also and accurate inside diameter of the crankshaft hole for the pilot bearing?

As you know I'm mating a ford T56 magnum to an LS engine and I'm trying to figure out whether I can use a bearing or if I need a bushing.

Thanks.

There are 2 different OD pilot bearings, but both have the 0.59" GM ID.
The GTO, 98-02 f body fit in the smaller inside flange of the crank. This is available in both bushing and bearing if you need to machine for ford input shaft.
The larger bearing fits in the outer flange, used on LS7, trucks, 2010 Camaros, CTS-V. Bearing only though, never seen a bushing.
You can find actual specs over at Rock Auto, or look up PN specs at a dozen places online.

Thanks, I didn't think about that. OD of outer bearing is 1.7031". And since my trans is Ford spec, the bearing has to have .680" ID.
