Review: **WOW** Now this is QUALITY A#1 DONT PROCRASTINATE BUY IT YOU WILL BE HAPPY !!! - What AMAZING quality, I have had such probs with my 69 Corvette 427, the mechanic had my factory Rochester rebuilt TWICE and apparently still NO GOOD. I replaced my fuel pump all my vacuum lines and more, and still NO good. So I figured I would order this, I thought at that price I just could NOT go wrong. I installed today, it is 100% IDENTICAL to the stock one, it comes with all kinds and sizes of jets, KUDOS what XLNT company indeed. So installed, pumped the gas 3 times, turned the key and that MASSIVE 7 Litre MONSTER finally came to life, and my God it runs PERFECT, all pre adjusted and set just right. THANK YOU SO MUCH !!! OUTSTANDING Do NOT hesitate on this it's a FANTASTIC value... 3 years of the car not running right, and here for under $200.00 ... GREAT !!

### ⭐ Poor quality

Fuel leaked out everywhere waiting for my refund don't purchase didn't work at all

### ⭐⭐⭐⭐⭐ Surprisingly good
*by J***S on November 4, 2024*

This carburetor was surprisingly good out of the box. The documentation is rather clumsy and all over the place, but you can find general quadrajet documentation just about anywhere, so reference that for your initial tuning. The float was adjusted correctly and did not have any issues with the upper plate. The carburetor bolted on and started up straight out of the box and required minimal adjustment. It is important to point out that the quadrajet carburetors do not handle high pressure well and these are no exception! I've found that these will take up to about 8psi at most before they push past the needle and seat and cause the leaking you commonly read about. You must either install a regulator to keep your inlet pressures down or run a fuel pump specifically designed to provide low pressure. DO NOT BLINDLY TRUST YOUR FUEL PRESSURE! Many of the aftermarket replacement fuel pumps are putting out too much pressure for the quadrajet, even if it is listed as a direct replacement! Always check your fuel pressures or buy a quality low pressure and high volume replacement. If you are looking for a cheap and basic replacement for your quadrajet and are not chasing peak horsepower numbers, these will work surprisingly well if you set them up correctly.
