Jeff, I believe you are thinking of the Corvette 327/ 340, 365 and FI versions.

[Jim Parsons]

Both engines use Hyd lifter, 275 HP has .399 lift and 350 HP has .447. The L-79 does get the new Quick Fuel carb if you want over the Holley.

The 1966 327/275 has a three carb option; Q-jet, AVS, and the small(er) Holley.

Correct, one bad little duce.. by the Byrd man,,,

Joe Santangelo's original 66 ht ran 11.11 on our 11.33 record with that carb. at the end of '73. That car was nowhere near what we have in STOCK today. (2.52 Muncie, 28x9 slicks, 5.13's with slapper bars, NO roll bar)
I started to build a 66 post car for SS/E ..where the record was 11.10 at that time, and you got to use a 585 Holley..That project got sidelined when the index system was rumored.
You could use the Carter AVS in 66, but not the Qjet (I'm pretty sure Mike Moller used the AVS on his SS/K wagon)
Larry Tores came out with the 67 post car with a Q jet, and after a while ,NHRA relented on the Qjet 66 car.

The SS/GT car that Byron Setters has ,is the Corvette 300 hp version (585 carb), with some HP taken off, compared to the Qjet. I guess he and Gary Hettler tried to get some more off for the 540 Holley Chevy II engine, which should be somewhere in between the 65 4GC version, and what he has now, but NHRA said NO..Enough of this.
There ya go..best I can remember all this.

I have been in the auto repair business since the 1950"s, and worked on a ton of these cars, I also raced a record holding ,1966 Chevy II, in SS/H in the 1980"s . The majority of the 1966, Chevy 327, 275 Hp engines in all body styles, that I have came across, had the Q-Jet carb! I even have the the original NHRA spec sheets, that I received from our Div 5 tech director, in the late 60's, showing all 3 carbs, available, and I tried them all. The Q-Jet was by far the fastest!

Jim and Eddie are correct.

The '66 327-275's had three carbs accepted: the small Holley (about 550-585 cfm), the Carter AVS (not the AFB) and the Q-Jet.

Until the QJets were accepted by NHRA, there were lots of '66's that were changed over to '67's. -Al

I just realized I had conflicting info in the same post.
The AVS was available on the Chevy II , also , but not The Qjet, according to NHRA, in 73-74.
I'm sure the Qjet would have been available on all body styles, but NHRA sure as hell wouldn't let us use it.
Incidentally, we were No.1 qualifier at the '73 World Finals in Amarillo , (using the 540 Holley) with the original h.t. "Bad Jose" car, which is now part of Eddie Chin's fleet in Rhode Island.

Man this has turned in to a very interesting thread!

Haven't seen this much tech talk on this engine for year's but I do know this. If this engine were available in a Camaro at it's current factor, I would build it for sure.

Nice going Danny!

PS Hey George! How are ya man!

Let's get this straight...
The q-jet was a 1967 release and prior to that you got your GM's with various forms of Carter carbs and Holley Carbs for single 4bbl and then there were 2x4 carters and tri-powers on assorted GM vehicles. In fact, except for the 3x2 'Vettes, the tri-powers were last seen in 1966 due to the introduction of the q-jet in 1967.
And just to be clear, I've not only worked at gas stations and dealer service bays, but I know my Uncle had a '66 Chevy II with a 327 / 275 and so did three guys I grew up with in Brooklyn and nobody ever heard of a 1966 anything q-jet from GM. In fact, my best friend's butt-buddy has some documents that will prove this is baloney. And I've got a lot of car magazines that can prove my point also. And they date back to 1965 and none of them mention a 66 q-jet except for the release announcement in the October 1966 issue of "Fast Cars and Big-Uns" which as you all know is the definitive source of all things GM in the 1960's.
Something smells rotten in Denmark and I'm going to get to the bottom of this with NHRA!

Actually there were a lot of GM cars with a Q jet in 66 and even some in 65. The 396 / 325 Impala had a Q jet. Also all of the SS 396 / 325 Chevelles had a Q jet , the 360 horse had a Holley. I also think there were a bunch of Buicks and Oldsmobiles that had Q jets and I would bet Cadillacs. I can't swear to a 66 Chevy 11 with a 327 but it wouldn't surprise me. In 67 everyone got Q jets.

[Mark Yacavone]

Jeff ,I guess you've never seen a 65 Chevy 396/325 with a Qjet, either then?
That was the first actual usage by GM.
1966 saw Buick, Olds and Cadillac use them.
The only Pontiac to use them in 66 was the OHC 230 6 cylinder.
The same basic carb was later used on the 500 ci Caddy, proving the versatility of the Quadrajet.

Jeff,
First of all, I am pretty sure your friend and his friend really appreciates that comment about their relationship.
Another thing. This has nothing to do with AMCs so let it go. You need to spend all of your energy getting your own stuff ready. LOL.
