« on: September 19, 2010, 07:21:50 PM »
What is the difference between the left side V8 and Z/28 plug wire stands?

My only understanding was the stamping on the Z28 and the color.  Z28 painted orange and the low po were black?

The repro suppliers have  different parts . One looks curved and one does not.

The original support was curved - good photos of it on page 76 and 90 in Jerry's book.

The ones on page 76 are 1967-68 parts, I believe. The ones on page 90 are a straight on shot so it is hard to tell how curved and how they differ from the standard V8 parts. Do you have a good pic of original? Thanks.

I thought the booster hose went thru the hole in the orange bracket - I forgot there was a second bracket. Was that hole (in the wire stand) just used on some models?

My (2) Pace Cars (350CI) have a metal tube with the hose for the booster going thru the orange wire bracket.
My Z's booster hose uses the long silver bracket.

Yes, there is a seperate Z/28 bracket. Z/28 had a seperate hose bracket as Kurt said. The hole was there for all brackets. The Z/28 and V8 model brackets were different somehow.

If you look in the Assembly Manual (section J50, sheet A4), you'll see the "straight" plug wire support bracket used on all small-blocks except Z/28, the Z/28 hose bracket, and the big-block pipe/support arrangement.

My guess is that the curve gives more room to get the valve cover off for lashing. The vacuum tube inside the bracket would aggravate the situation. Thanks John.

I am finding this thread very interesting because I am just starting the restoration of my intake manifold and related parts. Both wire supports were missing and a friend gave me these. I know they are rough, but wanted to know if they were correct before doing any work to them. The car is a 1969 RS/SS 350 (L48) with M38 and no A/C.

Is the stand on the PS supposed to be natural or painted orange like the DS?

To my understanding everything on the engine was Orange. It was painted as a completed unit.

The "magic decoder ring" for engine parts is the Assembly Manual; if the part in question shows in the Assembly Manual with a part number, it was installed at the assembly plant and will not be orange. If there's no part number in the A.I.M. and it was part of the engine assembly as shipped from the engine plant, it was painted orange (except exhaust manifolds, which were installed after engine painting, and aluminum valve covers and intake manifolds, which were masked off).

Orange it is then!  AIM says its part of the engine but no part number.

Yup - two photos below of my original.

John - I noticed you have spark plug wire separators above and below your tower. Is this the case for all SB's? And, is it safe to assume the same holds true for the passenger side?

Nope - long-time habit of mine, to keep #5 and #7 separated. The correct 3-wire retainer/separators are shown in the A.I.M. in UPC 6, sheet B9, item #17.

I have been recently researching the correct spark plug wire LH rear SUPPORT for my 70 Camaro SS350 long term project and found that most 1970 Camaro models were issued the support (marked "#5" with the oval hole) on the far right on my photo below. The support (2nd from the right marked "1970" and "#4" with the round hole) is identical to one on an original 70 Z28 w/1,100 miles.

I believe the one marked "#3" is for a 69 Z28.
