Need main jets for Q jet...

[GTX JOHN]

if memory serves.....we got them on E Bay from Ninja Fuel systems or
Quadrajet.com. They did not seem to vary any more in flow than OEM jets.

We ran a 86 Mopar with a Quad ten years ago.

That ‘86 MOPAR didn’t come with a Thermoquad? I used to work on those too. Part black plastic. Made by Carter.

No Sir.......I do know what a Thermoquad looks like as I currently own
over 250 of them and race Six Stock and Superstock cars of my own
with them (We will have four at Winters of our personal cars this week= Two SS/KA, I/SA,
N/SA).

My 86 360 Dodge Truck (Former Nat'l Record Holder) ran one sometimes.
Both brands were legal on that year at same HP

The 318 also often came with Qjet in that time period AND it is popular still with
318 GT racers who can claim it ( I have a dozen correct # ones). However, Last time I checked it was factored 4HP more than Thermoquad in GT.

No disrespect intended.....You know a lot more about racing than I ever
will and I enjoy your posts enormously!

I’m sorry, John. I don’t recall a MOPAR through my shop with a Quadrajet. Maybe it was “a California thing”? Due to their emissions restrictions, I saw a lot of California vehicles come through with different carburetors, etc. Certainly had much less spark advance. Very different advance curves in their distributors. Much of my business in the late ‘60s & ‘70s was “re-curving” distributors for performance & gas mileage. Very easy to pick up a CA vehicle 5 mpg. Taking away spark advance to lower HC emissions was a very common thing. That also kills drivability, power and gas mileage. There was a big fire at the plant where Rochester built carburetors, so GM had Carter build Quadra jets for a while. Carter would likely be the source for Q-Jets for MOPAR. Hard for me to imagine GM providing carbs to MOPAR. Old as I am, I have not seen everything.

I always wondered why Carter built so many Quadrajets for Delco Rochester.

The instructor at the GM Training Center, in Oklahoma City, told me about the fire.

I think it was '70 429 Cobra Jets that had a Q-Jet, too. Not sure what the SCJ had. Holley?
