I know Promax sells billet plates that take standard Holley jets. They also convert 4bbls too.
But see QFT and AED are they all.the same? Reason i ask is price point on the AED and QFT looks better.
Anyone use them?

I’ve used them both. Same quality on both.

Thanks if i am.unsure i now ask since so many things are junk now that were good before. It is good to know that the QFT amd AED will both work as good as the Promax.
You never know now days if even the Promax or anything is still good to go the way things are now.

Its amazing how far down the quality of some parts has descended. When doing a forum search on a product- a discussion here from as recent as 2019 may no longer be accurate as many manufacturers parts are now crap when maybe they were not a short few years ago.

Make your own!! drill/tap. 10-32 tap

Great idea R/T1968R/T . Seal all is a product designed to be completely submersed in gasoline- modern gasoline. Many think the standard JB Weld is gas proof. it is not and turns to goo.

I've drilled the stock holes that allow gas to get suck out of the bottom of the fuel bowls to fatten them up. I have a complete set of numbered drill bits from1 to 100 and a pin vise to put the smaller drill bits into use them in. I start with making the holes from.003 to .006 bigger, the driver sides holes are usually a little larger on the outboard carbs than the passenger sides are so I add to the stock size keeping the driver side bigger and then go drive it
I also have drilled and tap those holes for #6 brass set screws and then drill them, the blank brass set screws, to the size I want
Another easier way of fattening them up is to restrict, reduce, the size of the high speed air bleeds to make them run richer also
I tune the center carb for light throttle pressure low RPM cruising under 3000 RPM

Or you can do this.....
