| − | + | [[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. | |

| − | + | 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. | |

| + | {{Note1}}Often a specific distributor cap terminal was designated by the factory to be "number one". And the terminal designated as #1 will often be different depending on whether the ignition is points or HEI. | ||
| + | |||
| + | But in actuality, terminal #1 can be ''any'' terminal. As long as the piston is at TDC ready to fire (not on exhaust stroke), whatever terminal the rotor is pointing to can be designated to be #1. Just be sure there is enough rotation allowed by the vacuum advance before it hits the firewall or intake to set the timing. | ||
