Ignition Shielding Front Clip

Re: Ignition Shielding Front Clip

I'm with Wayne, I'm real used to seeing the "T" shaped ground on a '65, including 4 or 5 I've owned, one that I knew back to the original owner in the late 60's and later acquired.

Wow, now that's rare ! I have one that's NOS (MS / 238__24); agrees with the Delco Tech Spec book. Going to rent it out for flight judging . Even the '65 TIM&JG doesn't expect anything but a "236" can on small blocks. So you must have the base or L75 distrib 1111076.

Re: Ignition Shielding Front Clip

Hope I'm not hijacking this, but I'm also replacing the front clip on my ignition shield. The car is an early 63 and has the first type of clip, but it's broken. I have the proper new clip, but I'm wondering: should the rivets be stainless or carbon steel?

Happy New Year,

Re: Ignition Shielding Front Clip

in the for what it's worth dept. delco specs call for the '238 on the '076, engine distributor 250-300hp engine. '236 on all the hi-perf and SHP engines using the 087, 088, 069, 070, and 064 dist. 238 specs are 12.5 degrees, require 11.7-14 inches to pull full davance, 236 requires 5.7-8.2 for full advance. the 303-30 cnd 350 hp cams were both providing too little vacuum at idle to give full advance on these combinations.

L75. Who would rent one when the JG says it's wrong (even though we know better)?

Can't help you on the clip regarding change over. All I know is that mine left the factory with the shield I pictured above. Also, sometime in 65 they changed over from metal rivets to plastic ones on the top of the shield. It must have been on my car because I have one of each, again, original.

Too bad the JG doesn't reflect this.

I expect it will when it's revised finally. I believe most of the experienced mech judges are aware of it.

1964 ignition shielding hoveddel med riktig clip.jpgSo this is also the right shielding and clip for a 1964 special high performance as well?

Re: Ignition Shielding Front Clip

Yes Claus, it is correct for 1964.

Re: Ignition Shielding Front Clip

[QUOTE=Wayne Midkiff (3437);592730]Jim -- there's contradiction in those pages. Yes, Noland shows the new '65 top shield on pg 302 with the notch for points adjust, but the ground clip is the earlier '63L-64 style (GM engineering dwg of #3839334 on pg. 167). He goes on to say, along with this new distr. shield #3864671, they included a new grounding clip, #3864672 (one digit more than the new distr. shield. GM design dwg on pg.303.

Regarding the shield itself, when did they switch to the one with notch out for the points adjustment? Mine does not have the cut out that is shown in Jim's picture.

Re: Ignition Shielding Front Clip

Here's the sketch from John Amgwert's Spring '86 Restorer article.

Hmmm, let's see; now I have to "Go Advanced" ... then manage attachments (like before), then "add files" button, then "browse" (in my case, to desktop) .... then ???? I give up.

(10 minutes later) Alan -- was able to attach it but can't figure out how I did it [I went through so many false leads]. Will somebody please put a bullet through the head of this "upgrade" .

Is the clip in the picture for second design 63/64 the correct front clip for the L76 365 hp shield and air cleaner? The picture is from Wayne Midkiff (3437) and dated 12/31/2011.

Re: Ignition Shielding Front Clip

If the clip is solved, does that mean that ANT of the Repo people are using the correct diameter rivet head to attach it? Last time I checked, the answer was no.
