distributor 70-72

[Lyndon S.]

In judging how detectable is a distributor with out the old style points in them using one of the points replacement units Is there a really good one on the market that will pass judging?
Also what about the tach drive with the needle bearings is that something that is worth upgrading also?

EXTERNALLY, the Breaakerless SE conversion system cannot be discerned from stock. However, if a person were to open the distributor cap point adjustment window and peer in, the conversion can be detected.

The tach drive COUPLER and cross gear with needle bearing probably doesn't provide a lot of benefit over stock. However, it doesn't do any harm, either.

Hi Lyndon,
As Joe mentioned looking in the little door in the cap is the key.
At the same time the change was made to the 71 style distributor shielding the 'RFI shield' was added over the points. The judges should be looking for that by opening the door, so will see the breaker-less ignition parts too.
Merry Christmas!

Alan

The needle bearing tach drive is NOT detectable when installed and judged. As to whether it provides any functional improvement -- Joe already answered that.

You already have your answer to the points question. Judges should be looking for the RFI shield Joe and Alan mentioned.

What is the judging points loss without the factory installed ignition shielding covering the points on a 1970?

Jim,
The 1970's with the 3 piece shielding did not use and RFI shield. I believe that was up until VIN 11,500 or so. All later 70's , 71's and 72's had an RFI shield.
As I recall your 70 is very close to mine (#14803) so it has the 1 piece shielding so you would need one.
If you have a 70 or 71 LT-1 than you have TI and that would not require an RFI shield.

Re: distributor 70-72

Is anyone reproducing the RIF shield?

[Lyndon S.]

Re: distributor 70-72

Are the reproduction distributor caps judging well? Are they easily detectable ?

Re: distributor 70-72

Repop caps are easy to detect.

Hi Lyndon,
I BELIEVE I saw some original RFI shields, (it's 2 pieces that fit together), for sale at Carlisle last summer. Smart Parts 217-482-3393.

Re: distributor 70-72

I do not believe anyone is making the two piece RFI shield but some originals are available for sale - I paid about $25.00 for mine which still had the original sticker on the inside. I have not yet installed my RFI shield but am told that to do so I will need to also install the old style points with the separate condenser both of which I have not yet acquired.

You have been told correctly.

Robert --- I've got the opposite situation; bought this off eBay; a points plate and shield package, but missing shield(s?). Instruction sheet dated 8/72. It has the D112P points. I think the shield attaches to the screw holes at 7:30 and 2:30.

[Robert S.]

Re: distributor 70-72

Yes, that is the part number of the point set that I am told that I need. The two piece shield is held on by two screws that are the same size as used for the points and would bolt into the two open holes in the plate shown in your picture.
Makes me wonder how they set the point dwell at the factory as you clearly cannot use the window to adjust the points with the RFI shield in place - I guess they must have just set them by gap. It is no wonder the RFI shields were discarded at first tune up.

Re: distributor 70-72

what is the part number for RFI?
