{{Note1}}Starting around 1966-'67, not all cranks were machined for a pilot bearing, so be sure to check to see if the crank needs machining before installing the crank if a manual transmission is to be used. | {{Note1}}Starting around 1966-'67, not all cranks were machined for a pilot bearing, so be sure to check to see if the crank needs machining before installing the crank if a manual transmission is to be used. | ||

[[File:BCA-7109.jpg|thumb|150px|BCA p/n 7109 pilot bearing]]Pilot bearing is BCA p/n 7109 (available from [http://www.summitracing.com/parts/BCA-7109/ Summit] and Ken's Speed and Machine, among others) The GM part number is 15533265. The dimensions are 1.3780" OD x 0.5906" ID x 0.3543" wide (35 mm OD x 15 mm ID x 9 mm wide). According to Ken's, the cheaper p/n 6202 bearing may be used, but the crank opening may need to be machined 2 mm deeper. The p/n 6202 is 35 mm OD x 15 mm ID x 11 mm wide. The 6202 is available with shields on both sides to keep dirt out. | [[File:BCA-7109.jpg|thumb|150px|BCA p/n 7109 pilot bearing]]Pilot bearing is BCA p/n 7109 (available from [http://www.summitracing.com/parts/BCA-7109/ Summit] and Ken's Speed and Machine, among others) The GM part number is 15533265.

The outside of the crank opening is staked with a chisel in at least two places to hold the bearing in place because the pilot bearing is a slip fit into crank recess. | The outside of the crank opening is staked with a chisel in at least two places to hold the bearing in place because the pilot bearing is a slip fit into crank recess. | ||
