4 Barrel Carburetor for Rochester Quadrajet Carburetor 4MV 1904R 1906R 4BBL Carb Fits for Chevy Chevrolet 305 350 c.i Engine V8 GM Cadillac 1980-1989 Vacuum Secondary 750 CFM New with Electric Choke

After a little tuning it runs great out of the box I replaced an edlebrock 1406 carb with this on my 79 400sbc and it runs like a new truck. for how easy it is to install, the only thing to note is it doesn't have an air cleaner stud and the mixture screws on the base plate are a little hard to get to but that is mostly me not having a short enough flat head screwdriver, for the price and ease of installation it worth the cost

Choke worked great. Had to adjust idle, air mixture, turn down choke and purchase connector for electric choke. Drive ability is good. This was for a 74, 400 SBC. Don't be afraid of the choke issue.

Worked no problem right out of the box. There's a little play in the arm from the choke to the choke valve resulting in the valve not fully opening. It's like 95% open, but not 100%. I tried adjusting the arm to it's max but there's still a bit of play. The carb I took off did not have this play. It's an easy fix, if the carb is on the bench. I just don't feel like taking it back off the truck, but I'd say check that play, if it's there, fix it before you install it.

This aftermarket Quadrajet 4 barrel carb bolted on and started right up. Allows for adjustment and jet changes if needed.

Worked perfectly. Perfect fit, electric choke works great. Loosened up the secondary a tad , needed no other adjustments on my 1986 454 C.I. big block G.M. motor.

Casting flaw in base plate. Did not see until we spent months trying everything to get it to run right. Took carb off and noticed a casting flaw. This flaw has the media blast marks so this was done prior to finish/milling of the unit. Secondary air flap spring was broken needed to disassemble and reinstall spring. Quality control is lacking. Sent numerous messages through Amazon to get resolved and no response. Just want a new one or refund.

1975 Chevrolet 350 pickup. First off, I've been building carbs for 55 years. All Quadrajet carbs are pot metal castings, this is the FIRST aluminum casting I've seen. Very good quality made in China. I had to take the top off to see inside and I had to put my touch on the carb. There was an issue with the choke linkage fast idle cam portion, I had to replace with a used part that I had on hand. I also had to increase the jetting, the carb was to lean. Beside having to tweak the carb, the casting is well built. I would recommend to a gearhead.

It works good
