From dobbins book 69 L-46. Great reference book to have.

Re: 1969 L46 throttle bracket

The throttle return spring attaches to the lifting bracket?

Seriously?


Please tell me that those valve covers are on the wrong side as well.

Yeah I picked that throttle return spring out in two seconds; and I don't even know these that well yet.

Re: 1969 L46 throttle bracket

Hey thats great thanks for the pictures. As I suspected my bracket has been molested, now I need to dig one up any suggestions? And yes the photo from the book does show improper spring placement and incorrect valve cover location. Seems to me that if you are going to publish a book with photos they need to be accurate, beacuse some of us are just stupid enough to do what we see (Monkey see Monkey Do).

Re: 1969 L46 throttle bracket

I'm finding the 69 L46 is kind of an interesting bird in that the information out there for it is somewhat sporatic. Take the AIM for example. After showing base motor details, it shows the optional 427 configurations, and then shows the LT-1 as the optional 350. The radiator usage gets confusing (The TIMJG) has errors in that even, and the pulleys aren't well defined.

I'm sure there's a reason behind the confusion, it would be interesting to know what it is. Maybe simply the first year of the 350 Implementation or later than anticipated LT-1 introduction.

Something.

Tell me! It's about to drive me nuts!

Corvette Central has them; and I am in process of buying a used one from here. I think if you focus on 68-72 with Qjet, you will probably get what you need. Be careful though in this manner; I have found that many things list the 69 L46 as Sp HP, but at times they are really referring to the later LT1

Like John said and it makes that particular part choice incorrect.

In all fairness to dobbins, the captions mentions the spring in the wrong location. Guess the VC's got by though

Re: 1969 L46 throttle bracket

That bracket is also used on the 68's.

Is that type of throttle bracket used throughout the 69 L-46 production run?

Re: 1969 L46 throttle bracket

Yes I have been finding some issues where the books are either vague or just don’t show anything at all for the L46 option. That’s why this forum is so important. I just checked Corvette Central and I don’t see any listing at all for the bracket, they show the one for the standard motor as being discontinued but nothing for the "special high performance 350" they do show a diagram with the part number 353070 as being the one I want. So the hunt continues.

There were 3 different accelerator cable brackets used for Q-Jet-equipped Corvettes over the 68-73 period. For 1968-69, bracket GM #3921611 was used. It's the one pictured in the Vette Vues photo. This bracket applies to ALL 1968-69 Q-Jet equipped Corvettes.

For 1970 Q-Jet-equipped Corvettes, the bracket changed to GM #3972625. This bracket also became SERVICE for 1968-69.

For 1971-73 the bracket became GM #3992386 for all Q-Jet-equipped Corvettes. It also became SERVICE for 1968-70 Corvettes in 1971. It was discontinued from SERVICE about 5 years ago.

All of the above brackets were Corvette-only. They were not used for other applications.

Q-Jet-equipped Corvettes used a different bracket than Holley-equipped. During the 1968-72 period, the only Holley-equipped small blocks were the 1970-72 LT-1. These engines were also described as "special high performance". The 1969 L-46 used the same bracket as all other 1968-69 Q-Jet-equipped Corvettes.

Both the Q-Jet and Holley brackets are GM-discontinued. I don't know of any current reproductions of either.

If you haven't found this to be yet, you'll find that base/ HP and SHP are all over the place for 69 and 70 SB's. Refering to your bracket number example, I would suspect the base motor bracket is correct for your L-46 and that anything SHP would be LT1.

I'm sure the numbers are CC's own, in-house catalog numbering system.
