You need a distributor with a Reverse Rotation gear going by your description. Look at the DUI website in the link below, you'll have to select the 7000 rpm 351w distributor with RR gear from the dropdown box in the menu to see prices http://performancedistributors.com/product/marine-dui-distributors/" rel="nofollow - link |

If you look a little harder you might find this on the Summit website.  It looks like a generic picture but the part number is for a 351w RR with a blue cap M35820RRBL is the DUI number on DUI's website, same as the Summit number. Then you won't have to worry about swapping gears and getting the gear properly located on the shaft and most likely drilling a new hole for the roll pin https://www.summitracing.com/parts/dui-m35820rrbl/applications/?ibanner=SREPD2" rel="nofollow - link The BL on the end is for blue, you'll also find the same part number M35820RR with other color designators on the end like BK for black, RD for red for example and there are others on the Summit site too. |

Tazz - I made this swap on my 91 Excel (Barefoot). You didn't state if it was a 454 or 351. I assume (and the info above is correct for) a 351 Ford. If you are working on a 454, its rotation is reverse but its cam is NOT.... therefore for a 454 Excel you would get a standard rotation DUI. Performance Distributors makes the DUI and are incredible to work with. Their shipping was REALLY fast and they worked with me figuring out what I needed and swapping a reverse for a standard rotation in 2 days. They are terrific and I recommend you buy direct from them (Plus you can get Blue/Clear/Red - whatever strikes your fancy)! It is a great swap. Look at the other threads on CCFan about the swap. Keep the wiring straightforward as you use the harness. It will help for troubleshooting later if needed. ------------- https://tinyurl.com/y6t5e3bu" rel="nofollow - 04 Air206 http://tinyurl.com/9urzgls" rel="nofollow - 91 Barefoot 78 SkiTiq |

In your posts you've always said you had an Excel. You still haven't exactly said you have a 351W in the boat. Like Air206 pointed out, some Excels came with a 454 Chevy. It sounds like you're talking 351W so hopefully you checked the measurements as shown in either of the links below for properly installed gear height and didn't just slap the gear on without checking. Second link is easier to follow Maybe you were lucky and the holes in both gears were at the same height, maybe not https://performanceparts.ford.com/download/pdfs/DistributorGearInstallation.pdf" rel="nofollow - link https://static.speedwaymotors.com/pdf/547-8583.pdf" rel="nofollow - link |

Sorry about that I do in fact have a 351 w motor, also I work at a machine shop all measurements where checked , only difference was the roll pin size on the protec dizzy gear had to opened up slightly for the new hei shaft. ------------- Lake Wylie NC |

Now that it's public knowledge that you work at a machine shop, everybody anywhere close by will want to send you little projects or maybe big ones too Good job on the gear and saving yourself 80 bucks |
