| I Have two Davis Unified Marine distributors. One has a standard rotation gear. The other has a CCW rotation gear that I have in my 1985 2001 351w ccw rotation. Can I swap the gear from my ccw distributor to the new standard rotation distributor or is their a difference with the advance weights ? I know the module and pick up are the same. The standard rotation part # is M35820bl and the CCW is part # M35820RRBL. Thank You Joe |

The only difference in the 2 distributors is the gear. A distributor for a RR 351W rotates CCW and a distributor for a normal rotation 351W also rotates CCW. This is because the cam gear and the distributor gear are cut differently from each other on the 2 engines. So the answer is yes you can swap gears If you're not familiar with the process do a little reading about removal and installation of the gear on a 351W. Google is your friend, or ask here  |

Based on the part numbers you provided in the post, both match up with a SBF Windsor 5.8 engine. As such it is highly likely that the weight and spring assembly will provide identical timing curves (provided both units are bone-stock and unmodified). The last 2 letters indicate distributor cap color. You may want to exchange the "BL" unit for an "RD" unit as the red cap will make your boat go faster. Just sayin.....
