Major improvements from my worn out quadrajet. Came with the 700R linkage. I did have to adjust the float level, as well as the auto choke. Does not have an internal filter, so you need to purchase one of those….. and install it correctly. Haha. Factory air breather does not fit, gotta purchase one of those too. Fit and finish is nice. Easy to adjust and troubleshoot.

It arrived promptly and when I opened the box was pleasantly surprised it had such a nice finish. Overall great carburetor.

only minimal tuning was required. very impressed. ran very well as delivered , Choke , idle speed , fast idle speed and even mixture screws were adjusted very close to perfect.

Wow this thing is shining. It’s almost a shame to install it with out upgrading all my hoses. Dang it now I need more shiny stuff.If you are replacing a two barrel with this four barrel don’t forget the linage extensions.

I put this on my 66 thunderbird with a 390 and she fired up right out of the box. Idle was a little high but the mixture was almost perfect. I could not have been happier with the carb.
