Default converting to 1970 v8 points for model a

I saw in Les Andrews volume 2, on page 1-6 his comments for use of improved mechanical points used from a 1970 v8 & condenser. Does anyone know what the exact part #'s are. It looks like a good answer to replacing stock model A points which wear down so fast with teflon points contact. He discusses how to adapt the the distributor plate.
Does anyone have experience with this and know which part numbers he is talking about? Thanks, Jerbo

Well.....you have opened up a can of worms. That being said I have driven many thousands of miles over many years with this conversion. Most all the vendors sell the component parts to make the swap. Two ways to go are the new upper plate which the points and condenser mount to. The other is the lower plate. Many guys complain that the little "Z" shaped contact tang can misbehave and short. I just built a spare distributor and this time I eliminated the little "Z" tang. Like I say, I have had no trouble with this set up but many have.

I assume you mean the rubbing block on the points arm. Are you lubricating the distributor cam as specified?

The only time that I had the rubbing block wear down exceedingly fast was when I had installed a new "B" cam and didn't notice that the surface was quite rough, not as smooth as it should have been.

The V-8 points are from a 289, 302 Ford V8 from the mid '60's thru the early '70's. Buy the best (more expensive) ones they sell, NAPA is a good place to buy them.

Is this the correct part for V8 points that will work on a Model A?

FYI Go one step farther and look for Filko 75 U Point sets. They show up on ebay once in while. Neat thing is that they have a capacitor attached that eliminates the condenser entirely...Only problem is that they are obselete, but as I found they do show up on EBay once in a while. The 75 S 's are identical to the ones from Napa, but do not have the capacitor attached.

The modern points & condenser are no better performing than the original Model "A" points & condenser. I do not understand the need to convert to the new er stuff. Can somebody explain the value of using later model points & condenser?

I cannot tell you which is better yet. I did purchase the modern lower and upper plate with modern points and condenser.
I am making the change because of condenser problems with the original set up. I think the condenser in the original location (lower part of distributor) gets too hot and shorts. People in my club like the new set up. Others on various forums do not.
I will let you know.

The V-8 points are from any Ford V-8 from 1957 until Ford stopped using points except those with dual point distributors.

I find the original type easier to adjust, otherwise not much difference.

Easier to adjust for one. Readily available at any parts store. Better rubbing block. If they weren't a better design the '57 and later Fords would still have Model A points.

Go to NAPA and ask for their best 1957 ford V 8 condenser and points. Alot of the condensers out there are defective and NAPA seems to have the best...

Really? I find the opposite to be true.

Ford had a number of point designs between the Model A and the Y-Block.

I have been running the modern points with the wireless contact from Bert's for the last five years since my rebuilt. Still the same set with no problems. I lube the cam with a little Vaseline about once a month. No wear on the rubbing block. It's like discussing motor oil, the pros and cons can go on forever.

The truth about points.

First let me point out that my brothers 31 Coupe has been running the same points that came with the car in 1970.

Yes you read right. 1970

Points can go bad, but that is rare. If the cam is smooth and properly lubricated the wear block will go a very very long time. How many guys are putting 10,000 to 20,000 miles on their cars- not likely.

I know you guys like to to fix stuff and in the old days you were supposed to change points regularly. Well you are just making extra work. New points need to be adjusted frequently as the wear block wears to the cam surface shape.

Do yourself a favor, stop playing with the points. If you have Ford and Standard points on your car run them till they actually fail. It is likely you will not ever change them.

I have a jar full of used points I took off of dist I took apart. Several were low quality stuff and the point material was oxidized. All the Ford and Standard had nice shiny point blocks. I would use any of them except I have several NOS Ford sets so I am using them.

Which points to use ? Yep, heck of a question

The originals are just fine. A good quality set will last and they are easy to adjust. There apparently was a batch of poor quality condensers recently. [ I went thru 5 in a row, just because they are 'burn-proof' doesn't mean much]. I think a spare connected to the coil just in case is a good idea.

The modern plate is just fine. Its hard to find quality points and condensers today though. The expensive ones are the way to go. Unless you have a plate with an adjustment slot [ or cut/make your own] they are harder to adjust. I also recommend the 'wired' plate or just add the correct wire.

I think all that can be bought today is the Model B points cam and some are ground pretty rough and wear the points quickly until it smooths out. I've spun and polished a couple. Plus some new points have 'soft' rubbing blocks and wear quickly. The expensive ones seem better.

Ford V8 points are Ford V8 points. Just pick a year from the mid-50s to the early 70s.

The arguments for the modern points are bogus in my opinion.

agree with Bob Bionde.
never any problems with original type points here.
30 years ago I fooled around with modern points and wireless lower plate.
more trouble than they were worth.
lots of long tour miles with original type, no problems.
never had to use the spare distributor that rides under the seat.....

What ever, don,t butcher an original upper plate, buy the one made for the later points. You will likely go back to original system. Has any one tried it? this is a 40 year old mod. that sometimes works today. Not better just different. Thousands have done it and asked Why?
