I just got my 1974-75 Olds mo-bubble Q Jet from Chicago Carburetor probably out of a Toronado, Hurst W6 or whatever and it's easy to varify that it is a 800 or a 750 because a Qjet only came in two sizes, if anyone says different they are full of Ka-Ka. I test fitted to my air cleaner base and clears like the original. It supposed to be Pontiac linkage on it. The throttle arm pivot is in the right spot but, mounted to the inside ( can easily be swamped ). They say it was bench tested and flows 830+ CFM. SMI and Jet power said they would build me a carb for 750 bucks + 200 if I wanted everything plated to look nice and it would take 16 weeks. Chicago Carburetor charged me 600 and I got it in 1 week and looks brand new. We will see how it performs. I had to monkey with my crank timing gear, it was to tight along with my balancer. The stroker crank is a couple thousandths bigger than stock ( the balancer plopped right on a stock Pontiac crank ) and Of course the windage tray requires spacers and the stock water pump divider won't fit my Kaufman timing cover. I will know next time.
