## Questions & Answers

**Q: will this  work  on 350 with cam**
A: It should be okay, for most cams. Mine is a 5.7L (350) built as an LT1-1. In a 1987 Camaro. Everything hooked up, and it runs well.

**Q: how does this work with the on board computer of the 84 caprice. will it be read by the computer and not make the check engine ligth stay on.**
A: This carburetor works well with my 85 Camaro and should work on any V8 that GM made from 81-89 with the factory onboard computer.  This model has a built in throttle position sensor,  which possibly could be setting your Maintenance Indicator Lamp to be on, but most likely,  it won't.  The other connection uses the pulsed output from the computer to alternative between lean and rich to achieve a computer controlled mixture. ( The solenoid energized is lean, disengaged is rich). If your check engine light is on, I would check the 02 sensor, the MAP sensor and the Coolant Temp Sensor. It also probably has a knock sensor in front of the starter, but they dont usually set a code in the ecm.

**Q: I have ran new exhaust and no longer have O2 sensors. Will this carb run right or should I buy one that’s not electronic**
A: I don't think so. The ECM will be looking for a signal from the O2 sensors. I think it would be better to go to a non computerized carburetor (ND4478) but you will also need to change the distributor to one that has a vacuum diaphram.

**Q: Will this fit a 86 monte carlo v8 305 Ls**
A: yes it will as long as you still have the computer on the car.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent value, HIGHLY RECOMMENDED!!
*by E***. on July 19, 2018*

I admit I was highly skeptical of buying a rebuilt carburetor. Q-jets are notorious for either working well... or NEVER working. There's no in-between. So I took the chance, keeping my fingers crossed. I installed on my '87 Monte Carlo SS, with 86k miles. It took an hour, swapping some parts and brackets from the old to the new. Triple-checked everything, and after 10-15 seconds of cranking it fired right up, was smoother than the old, dying carb. After setting hot idle, took it for a test-drive; excellent power, secondaries were perfect, it's VERY smooth idling, and now starts at the turn of the key. No stumbles, no issues whatsoever. Before this I'd been seriously considering replacing the engine, but now I'll leave it alone for a while. EXCELLENT VALUE, HIGHLY RECOMMENDED!!! 😎

### ⭐⭐⭐ Not the same product as advertised.
*by W***R on April 11, 2019*

Was advertised as a new carburetor and when I received it it was a rebuilt.

### ⭐⭐⭐⭐⭐ Very IMPRESSED! Great buy!, plus came with Lifetime Warrenty!
*by D***E on April 14, 2015*

I haven't started the car that I bought this for, but I was very impressed by the quality of the assembly. It looked like it was brand new, I didn't see any marks from when it was previously installed on another engine. It did get damaged during shipping, it looked like the carrier had dropped the item and the electric choke was broke. I called tech-support and they had a new choke sent out the next day. For the price, I couldn't rebuild my original carburetor and replace all of the items that this one had, plus this one looks brand new. All of the vacuum ports are identical to my original.
