Should I replace the whole distributor or use the conversion kit such as available on Ski-Dim? Anybody here done the conversion themselves? ------------- 1974 Mustang |

I have done a few of those conversions, the directions are pretty good. The only reason to replace the whole dist. is if its got lots of hours on it and the bushings are shot. The rotor should have very little side to side play. should be clean and without corrosion. Then I would certainly re-use the dist.

slack in the shaft not really a factor w/conversion,min. side to side movement is ok. no slack or movement is allowed w/ breaker points due to dwell and timing concerns.put the mallory module and the power filter. this stops a voltage spike from smoking the module. mallory also recomends their coil #MAA-29216.filter #MAA-29351 ,i think the output voltage is considerabley higher,had to replace my new Accel 8mm wires because of leakage,bought a set of Taylor 9mm no more light show or Gottcha's . instant start and a 400rpm idle,simple but cost effective upgrade..........boat dr ------------- boat dr /diaries/details.asp?ID=4631 - 1949 Dart /diaries/details.asp?ID=1533 - 1964 American Skier |

I replaced mine about 8 years ago, it was the best $90 ever spent. Better starts, and more responsive throttle. Keep your distributor if there are no issues in wear and timing advance. ------------- Tim D |

conversion kits are all right but are not that accurate or consitant cyl to cyl as far as timing is concerned. Worn bushings will not increase or decrease rotor movement as it turns it will effect the the gap between the terminal post and rotor as the shaft no longer spins comcentricly but not a enough to really make a difference.
the main reason to go to a new dist over a point dist is the accuracy and consistantancy in firing cyl to cyl. Making it easier to adjust the carb for easy starts and better overall performance and then matching it to a high output coil improves fuel ecconomy and improve performance even more. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

I believe you want to use a YLM-554-DV for a reverse rotation engine or the optical version YLU-554-DV, the CV version is a standard rotation model. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

Hey 79
I see you've changed your way of thinking. Now you say a DV is for a reverse rotating engine. I do believe you got it right. You've flip flopped on this over the years but I say you're right this time. I think you spelled everything right too. Good job |

sumitt does not stock that rev. rotation dist. very easy job to r&r old gear,boat dr. would not use the optical pickup,reason???????older motors deal w/blow by,a little oil film on said optical pick up renders it blind...not so w/magnetic,have installed many in clients I/O and inboard applications no problems..........boat dr ------------- boat dr /diaries/details.asp?ID=4631 - 1949 Dart /diaries/details.asp?ID=1533 - 1964 American Skier |

Good to see more posts on this question...I was a little shy in asking another question but I'll jump in again...
Our starts on the 80SN are inconsistent and sometimes we'll get nothing at all. The 351 engine is stock, nothing changed, just a rebuilt Holley carb. After reading a few posts on ingintion systems, it seems we'll benefit by switching to eletronic. I've read there is improved performance in completely switching vs. using a conversion kit... My question is, what would be the price difference in doing each one correctly and completely...and how noticeable will the performance be? That will help me justify which path to take. Thanks! |

they swithed to a new numbering system so if you gave them the DV version then it should be right.
Keno I went back and checked my old post instead of going to the catolog this time. Boat dr.... your all wet on this one... blow-by will not effect the distributor in anyway shape or form and will not increase the amount of oil going up the shaft of the distributor. But then again you wouldn't want to spend the extra money to have a superior ignition system. That provides faster triggering, consistant accurate firing cylinder to cylinder and has fewer parts to go bad or break. The weakest link in a magnetic trigger dist are the two wires going to the coil that energizes the pole piece. Because the mechanical advance is always moving the base plate back and forth it causing the leads to work harden where they meet the coil windings and eventually they will break. An optical pick-up doesn't have the coil or wires to break or go bad. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

scott your looking at about twice the price for a magnetic pick-up dist vs a conversion kit and about three times the price for an optical version that I run, The HEI unit that is iavailable is about 3.5 times more once you buy the gear but your getting a new coil as well. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

79 you could be rite,omc tried the optical system for their outboards,cost them a lot of powerheads due to misfires and other related ignition problems. as far as blowby ,optical works on a light and a pickup the window tells itwhen to fire.no window no fire,oil film on pickup tells the sensor its not time to fire,omc had this problem,from blowby at the upper crankshaft seal. magnetic pickup,tho not as accurate nor as expensive will work just fine. 79nautique remember we are replacing a points type ign. in my way of thinking that is old tech. vs. new tech. donyt you agree?????? and the points work just fine for the rpm limits that we choose to live within.........btw what system are you running in you motor,will send you pics of my boat and how i spend my money,its called cost effective high performance.331 stroker 400 FT.lbs and 350 HP,wanna see what dist. i use,stock Mallory w/conversion kit. it alows me to buy thigs that make serious HP. gt 40 HEADS,Edelbrock,Holley and a brand new 331 stroker built by Houston Performance,also cam designed for this motor and application by Cam Research inc.plus new OJ 4 blade,wah buddy i aint cheap i just spend my money wisely.........boat dr ------------- boat dr /diaries/details.asp?ID=4631 - 1949 Dart /diaries/details.asp?ID=1533 - 1964 American Skier |

This is for grim over there in the netherlands.
If you have the old distributor in your hands look at the teeth on the gear. If they go this way/////, it's a LH engine. If they go this way\\\\\, it's a RH engine. Whatever you decide to get, make sure you get the right rotation or you'll be screwing with swapping gears. Try Discount Inboard Marine (they advertise on this site) and they'll get it right for you if you give them the correct rotation. keno |

I use a mallory YLU-554-DV unit in a 351W and have just as much torque as your's and run 51-52 GPS with D8OE stock heads, mallory high output marine coil and a comp cams cam, balanced motor, re-jetted 4160 holley sinlge pump, edlebrock performer intake turning a acme 470 three blade prop.
Now I do have a set of heads being working on that I'm going to install later with new edlebrock polished alunimum exhaust manifolds. That is once the D0OE heads get the 1.90/1.60 farrera valves with .600" lift springs and scorpion full roller rocker arms on screw in studs with guide plates. Are machined and are ported to match the intake and exhaust manifolds then polished to let the new high lift cam breath at 6K. But you really should stick with the larger combustion chambers that the gt40's have, you really don't need the extra compression or a high lift cam in your 302 stroked block. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

Billy,
I spoke to correct craft in 1978 they produced left and right hand engines. I dont know what my engine is. Can you have a look at my pictures? http://www.westerengh.com/ski/tag.html I think i have a right hand? So i have to buy a right hand distributor ------------- greatings from holland |
