Ordered it yesturday at noon from summit and already got it today!
Looks awesome My question is should there be up and down play on the shaft to the housing? About 1/16 inch up and down play. It looks like there are set screws to adjust it? Anyone have this? |

Steve K. (Air 206) just installed one in his 91 Vee Drive Barefoot Nautique last week. They dialed it in at the White Lake, NC reunion. Go to the White Lake Thread and PM Steve for questions. TBenj and JoeNY are very familiar with their application and operation.
Steve is in Virginia. You will be in good hands. Donald |

Cameron:
My Performance Distributors DUI for the 454 was not adjustable. Are there instructions that came with yours for fitment? I was so new at all this that I actually read mine.... I know, crazy - right?. Mine said that there should be up and down play in the distributor shaft and it should engage but NOT bottom out - as that will cause damage. It came with a flat fiber washer to act as a spacer between the block and the neck of the distributor shaft. Hope that helps. Look at Jpass' write up for his "ProTec Ignition Swap" . The 454 has slightly different issues and I'll make a modification post sometime soon. Feel free to PM me.... but I warn you, I know very little..... but it ran! Ha! |

I can't recall if there was any free play on my DUI shaft. I do know that I did nothing to the DUI shaft prior to installation. I'd give Performance a call and run it by them (901) 396-5782.

I installed mine in my 351W about 11 years ago and do not recall any play or adjustment. I do remember that the instructions mentioned to bump the starter if needed to engage the oil pump drive and that was one of the top 10 mistakes of my life. The brass teeth on the distributor somehow sheered all but one of the hardened teeth off of the camshaft. Chewed up the brass as well. That is the reason that I now own a cherry picker or engine hoist. Oh, any by the way, Comp Cams has reverse cut blanks that can be custom ground for our reverse rotation motors.

I seem to recall some play, maybe less than 1/16".

Got the dui installed this weekend and it really does "fire up with gusto!" my brother in law helped me out and made a great suggestion. he said maybe now we should get a new air filter.
  Now i got all kinds of random wire harnesses and sensors that are not plugged into anything that i want to get rid of. ill try to take a pic but it seems like i need to keep the electric choke, oil pressure and temp senders. is there anything else? |

The only sensor you lost in the ProTec swap to DUI is the knock sensor. You may wish to review JPASS' post as it is a good review of the wiring and diagram.

120 bucks or so and you can buy a new harness that omits all the old protec stuff.

The oil and temp switches and knock sensor are not used anymore. You can cut off all the old connectors just make sure any wires that are still hot get the ends covered in shrink tube, If you used JPASS'es write up then there won't be any hot wires left over. If you wanted to get creative the oil/temp switches are wired together and could be used to drive an alarm or dash lights (or shut down the motor) if a low oil or high temp condition occurs. They short to ground when a failure is detected so just use them as the low side of the circuit. |

I think i have alot more wires than just the ones in JPASS write up.
There are gadgets that are just laying on top of the manifold that have been there since we bought it, the previous owner said they were for the EFI but he converted it to carb, anyone know where i can find info on that? Also when i disconnected the coil pack the bracket with the starter solenoid and fuses also came disconnected along with another box of some sort. i don't know what that is also.  You can kinda see a few of the plugs im talking about here. |

Ah, this was a TBI to carb conversion as well, not just ignition. Yea, probably more wiring.

Looks similar, Mine was a 454, non-EFI - Check with Townsend at Nautiqueparts.com.
He'll hook you up (discount for being a member too)...... (You don't have to swap, though. It gives you a chance to "clean it up", and make sure you don't have resistance issues and voltage drop in an old harness. Mine was good, without voltage drops but I didn't have all that.) |

Do you know which schematic matches your harness?

Definitely not worth the swap. It's all neatly soldered and bundled up now. Plus, I had several non-original senders wired into the Pro-Tec Circuit Breaker which is not accounted for in the new harness.... so I would still have a spliced harness.
 Runs AWESOME! |

Cameron,
With a carb and standard ignition, the choke is wired into the switched ignition feed from the key switch. |

Normally, it just taps into the ign fd wire in the harness next to the carb.

It needs to be connected to the purple ignition feed wire from the dash. A full 12v needs to be sent to the choke so whatever wire you're using to supply the DUI will be fine as long as running voltage is above 12v to both.
