"50 Merc distributor choices?? Stock, MSD, or Modified Chevy
For my AV8 pu with '50 Merc, which distributor would be best choice? Stock, stock with Pertronics kit, MSD, or a old Chevy modified which would allow mechanical spring changes and vac adv.? Tell me your horror stories and what worked best. I'm sure others would be interested.

Re: "50 Merc distributor choices?? Stock, MSD, or Modified Chevy
I recommend the SBC unit, This can also be converted to electronc. I recommend 20* all in by 2000 including the initernal. Then 6-8* vac. Now the vac will be all in at all times, except at WOT. This is a starting point and is close for a 276, 8.5CR and L-100.
My Friend Richard is doing some experimenting with this vac adv. You should also Monotor the A/f under WOT and cruise conditions. Charley NY can do this. |

Re: "50 Merc distributor choices?? Stock, MSD, or Modified Chevy
I hear good things about the L100 cam but my stock Merc cam measures good - less than .0004 diff in lobes. This will be a daily driver and not a high RPM motor. What do you think? Would I be foolish not to change it out during the rebuild?

Re: "50 Merc distributor choices?? Stock, MSD, or Modified Chevy
No Keep the stock cam or find an EAB cam (stock52-3). Get your pistons close to the heads< Find some EAB heads as well. This will increase CR as well. This will improve mileage too.
Good luck Ol' Ron |

Re: "50 Merc distributor choices?? Stock, MSD, or Modified Chevy
Got the EAB heads - abt 63cc's compared to 84 for the 8CM's Will do a check for interferance when engine is put together. The shop I took the block to is really busy with modern stuff so not sure when they will machine it. I'm a little nervous since they do so few flatheads.

We just shipped number 256 of the chevrolet conversions. More info at http://www.lindertech.com/bhrs/flathead_chev.htm Curved to be all in at 2500 rpm at 24 degrees ( has proven to be perfect) and can have adjustable vacuum advance if needed. Makes a flathead feel good for sure.......all units now have the merc ford extended shaft to fit both timing covers and factory clamp down. Last edited by BUBBAS IGNITION; 05-27-2010 at 05:53 PM. |

Re: "50 Merc distributor choices?? Stock, MSD, or Modified Chevy
24* may work well for some engines, especially those with a lower compression. However If you purchase a distributor from Bubbas, check it out very well. His quality control is lacking.

Re: "50 Merc distributor choices?? Stock, MSD, or Modified Chevy
The MSD has the same advance mechanism as the SBC. Severalpeople make advance parts for them including adj vac canisters.
Most engines run a lean mixture during cruise and require more advance. Under WOT the adv must be retarded to prevent detonation. especially in an engine with Hi compression. |

Re: "50 Merc distributor choices?? Stock, MSD, or Modified Chevy
Charlie/NY fixed my GM dizzy for my 8ba. It's a points dist. but works verywell. Seemed abit tough to get dialed in but I had a few other issues going on at the same time. It's in a'47 tudor (Ford). I'd still be scratching my head if not for Charlie. LOL!

Re: "50 Merc distributor choices?? Stock, MSD, or Modified Chevy
This is the kind of reply we get when the owner is satisfied with the performance of his vehicle. My son bought a used 4 wheeler for his forestry business. We been using it for about 5 years and it seemed to run OK. A week ago it wouldn't start so it went into the shop. The thiing runs like is got a blown Hemi in it. Not sure what they did, but obviously it hasn't run right for a long time.

Yes , i agree beats me what happened here as well. I really didn’t know what to think when I first read the post on the quality of our ignition products etc. However I felt compelled to just leave it alone and go on. I have always said email needs brakes so the writer can reread what he or she actually said before sending. I am sure we all have sent something in haste and the next day wished we hadn’t said what we said.. However, Later in the week I felt otherwise and feel like I should respond to the post. Our reputation and internet presence is everything to us ! And to see someone question our quality is shocking to say the least. We spend a great deal of time on product quality and would like to think we improve each and every day. Have we ever had a problem,? Sure we have !! However our company policy is “ fix the customer and fix him now”. After shipping 256 of our flathead conversions I can honestly say we have had only a handful of field problems and to my knowledge they have all been fixed to the customers satisifaction . We not only do ignition but also recondition electronic fuel injectors and ship hundreds of products each and every week. I did build Ole Ron a distributor , thru a friend of his ( to the friends specifications) as a gift for his contributions to all of us . This was done as a gift thru the friend and myself at no-charge what so ever! I asked ole Ron with a PM for, at the very least a explanation of what he meant by poor quality and have waited a few days for a private reply. As a frequent contributor and tech service for any and all that ask i think i deserved a private reply before the first post. ! I would love the chance to rework the distributor to Ole Rons total satisfaction......send her back with a list and i will write a tech article on each and every function that makes you doubt our quality. After 19 years of providing automotive service, never have I had anyone question our quality! So in the above post using the word “Ouch” is very fitting. OK, with this said and done at the very least now I feel better ! If I can ever help anyone just drop me a email. Or use our toll free 888-809-3835 and ask for Bubba.

Kinda back on the subject of ingnitions Can a 221 be converterted to Chevy distributot too?
I've seen some internet articles (not specifically for the 221) that use the 8ba timing cover, machined Chevy distributor, 8ba drive gear....what I cannot seem to find is how to adapt to the cam? |

Re: "50 Merc distributor choices?? Stock, MSD, or Modified Chevy
I've been trying to think of a way to reply to these threads and then I got hit with a misunderstanding about the direction about the barn.
As far ad my comments about Bubbas Distributors, here's what I see with my bad eyesight. I've been working with several people developing the perfect ignition system for our Flathead. Unfortunately this requires some consideration about the intake system and the combustion chambet configuration. I didn't want to get into this much detail, BUT! I recieved Bubba's distributor and have to admit it looked great. I went to install it in an engine and noticed that the body was machined without a stop to locate the drive gear. Noe I have a lathe and making a stop was easy. GHowever most people dont have Lathes. Jim was informed of this and offered to fix it. SOOooo when I said his quality control was lacking, I wanted you to check out the unit. As for the actual operation of the distributor, I can't say, I havent checked the advance curve yet. It's important to note that we need people like Jim, because he fills a need for our hobby, but he needs to make sure he keeps his quality up a stay abrest of continuing research in this area. Keep em runnin |

Re: "50 Merc distributor choices?? Stock, MSD, or Modified Chevy
I recommend one of Bubbas sbc converts, hooked to msd 6, simple to the point and last forever. Used msd6 boxes arent very spendy anymore and are damn near bullet proof.
No ballast resistor, no load on the points, hot coil, big gaps, win win win! |
